Xiao Yao said that he was willing to try, so Sam did not accept the ten cards on the table and directly started the second round of dealing.

The second round of cards is still four players and a dealer a total of five positions, the process of dealing cards is the same, nine cards and a buckled up hidden card, the last ten cards are dealt, Sam unveiled the hidden cards in front of him to Xiao Yao to see, only to deduct all ten cards.

"Please!" Sam waved his hand after closing all the cards.

"Here!" Xiao Yao still followed the order of the first round, reached out and nodded on the leftmost card pile on his left, "Five hearts and eight spades!"

"Right, go on!" Taylor said directly.

He saw the process of Sam's cards just now, and remembered the two cards in the position in front of Xiao Yao, so he didn't bother to pick them up and check them again.

"Here, Ten Clubs and Ace of Hearts, Black Jack!" Xiao Yao moved his finger to the right.

"That's right!" said Sandra this time.

"Here, the King of Spades and the Three of Hearts!" Xiao Yao's fingers moved one more position.

"That's right!" Raj nodded as well.

The people in the card counting group were watching, and anyone could remember a few cards casually, so this time everyone didn't take the cards to check, but just verbally announced that Xiao Yao was correct.

"Here, Block Seven and Block J!" Xiao Yao's finger moved to his rightmost position.

This time no one spoke, and Sam looked up at Yan Ke.

In terms of position, Taylor, Sandra, and Raj are the two cards that are confirmed to be closest to the position they are standing, and the closest to Xiao Yao's rightmost pile is Yan Ke.

"Don't look at me," Yan Ke said with a smile, "In order to show fairness, the three of us don't participate in Yang's assessment! I don't believe any of you can remember four cards!"

"Alright!" Sam nodded, "That's right!"

After Xiao Yao clicked the two dealer cards in front of Sam, Sam nodded again to confirm.

After the third round of dealing, after going through the exact same process, Sam said to Xiao Yao: "Let's talk about it together this time! If there is something incorrect, we will point it out, if you don't believe it, we will open it for verification!"

"Okay!" Xiao Yao was as good as a stream, so he reported all ten cards in the original order in one go.

"OK, it's all right!" Sam nodded, "but that's just the first very easy step, now let's test the second project." There are now 30 waste cards used, please tell me how many 3's have appeared in these 30 waste cards!"

"Two!" Xiao Yao stretched out his hand and pointed at the two positions on the far left and the second on the right in front of him, "Here, square three, here, heart three!"

Now there are 30 discarded cards, which are dealt in three rounds, and there is an interval between them, and even if the people in the card counting team feel good, they are not so sure, so they pick up the cards on the table again to verify.

"The three of the cubes is here, there are no other threes!" Taylor picked up the six cards on the far left in front of Xiao Yao, looked at them, and nodded.

"Three hearts are here, and there are no other threes!" Raj picked up the six cards closest to him and looked at them.

"No! no!" Sandra announced, checking the two piles that had not been spotted by Xiao Yao.

"No, either!" Sam looked at the six cards in front of him, nodded and smiled, "I'm confident in your memory now, but we're not done with this test yet, I think we should finish it anyway!"

"Of course!" Xiao Yao smiled and nodded.

followed by the fourth and fifth rounds, and Xiao Yao still answered all of them correctly.

"Now I have two cards left in my hand!" Sam said to Xiao Yao with the last two cards, "Please name the value of these two cards, the time limit is five seconds! Five, four..."

"Hearts 2 and Ace of Clubs!" Xiao Yao said.

"Awesome!" Sam applauded.

"Thank you" Xiao Yao smiled and asked, "Is it over?"

"I'll ask one!" Sam was about to nod when Taylor suddenly interjected, pointing to Xiao Yao's leftmost card stack, "Can you name all the ten cards here now?"

"Tate!" Sandra said with some dissatisfaction looking at Taylor, "Jan has done a good job, don't make things difficult!"

"Don't get me wrong!" Taylor said to Xiao Yao, "When you got Sam's last two cards right, you've already passed our memory test!"

"Understood," Xiao Yao smiled, "Please give me a few seconds to recall!"

"Looks like you really can?" Taylor was surprised.

"Maybe I can do more!" Xiao Yao smiled.

"What do you mean?" said all four of the members of the card counting group.

"Diamond two!" Xiao Yao pressed his hand on the first card on the leftmost card pile, and after saying the suit and points, he turned over the card by himself.

The onlookers looked at it, and sure enough, it was square two.

"Plum Blossom Four!" Xiao Yao said, and opened the following one again, and sure enough, it was also Plum Blossom Four.

"Six of spades, 9 of diamonds..."Xiao Yao reported one flip and flipped all the way.

The four non-Huaxia members of the card counting team all showed surprised expressions.

"Block three!" Xiao Yao flipped through the last one, and sure enough, it was also cube three.

"Awesome!" all four exclaimed.

"Seven of spades!" Xiao Yao didn't finish, continued to report a suit and points, and turned over the top card of the second pile of cards on the left in front of him.

"Isn't it?" all seven members of the card counting team looked incredulous.

"Hearts 10, Club Q..."Xiao Yao said one by one, and quickly turned over the second pile of cards, and moved to the third pile.

"Oh my God!" Raj, who rarely spoke, was dumbfounded, "what did I see?"

After the ten cards in the third pile were turned over, Xiao Yao moved his finger to the rightmost card pile in front of him, and his mouth was naturally not idle, and then, it was the dealer card in front of Sam. In the eyes of the seven people with a look of hell, Xiao Yao turned over all fifty cards, and there was no mistake in the suits and points recounted in his mouth.

Including Yan Ke and the three of them, the seven people next to him all looked stupid.

"Xiao Yao, you are such a monster!" Yan Ke said to Xiao Yao with some incredulity.

When they were training in the Olympiad national team, Yan Ke and the others already knew that Xiao Yao had a good memory, but they didn't expect Xiao Yao's memory to be so strong.

"Yan, what did you just say?" Taylor asked Yan Kedao. Under Yan Ke's excitement just now, he spoke Chinese, and he didn't understand.

"I said that Jan is a monster!" Yan Ke explained in English.

"That's right!" said Taylor, "Jan is a monster indeed!"

"Yang, do you have superpowers?" Raj looked at Xiao Yao and said, "Just like those superheroes in comics, because they have accidents or have been genetically modified, they have superpowers?"

"Of course not!" Xiao Yao shook his head with a smile and said, "I'm just born with a good memory! If this is a superpower, then this superpower is innate! But my memory doesn't seem to exceed the normal scope of human beings, so it's not a superpower, right?"

"When we met him back then, he had a very strong memory, but it didn't reach this level!" Yan Ke said, "Maybe he has been preparing for the past few years, and has purposefully exercised his memory in order to go to the casino by counting cards?"

"Sort of!" Xiao Yao smiled and nodded, "Is memorizing music scores, lyrics, scripts, lines, and scripts considered to exercise memory?"

"Okay!" Taylor calmed down and said to Xiao Yao, "Yang, we admit that your memory is very good, better than all of us, and you must have passed our memory test." But card counting isn't just about good memory, so we're going to move on to the next assessment!"

"No problem, what's the next assessment?" Xiao Yao said.

"Numeracy," Taylor said, "mental arithmetic, to be exact!"

"I'm sure I'm okay with simple calculations, but I may still lack knowledge of advanced mathematics. Xiao Yao said, "So, if it involves advanced mathematics knowledge or formulas, I hope you will explain it to me first, and then test it." I am very confident in my learning ability, and the learning process should not take long. ”

Although Xiao Yao studied advanced mathematics when he was in college in his previous life, he only took two related courses as an undergraduate, and the content he learned was definitely not comparable to that of these master's students in science and engineering.

"No, there is no knowledge of advanced mathematics, just simple calculations!" Taylor said, "The difficulty is in the number of calculations and the prescribed time. ”

"OK, then come on!" Xiao Yao said.

"I'll come!" Sandra walked to sit down opposite Xiao Yao, took out her mobile phone, operated it, and placed it on the table between the two.

"Timekeeping?" Xiao Yao glanced at the screen of his mobile phone, found that the screen displayed a stopwatch interface, and asked with a smile, "How long is the specified time?"

"The sooner the better!" Sandra said, "I give random questions, and the difficulty of the questions is not necessarily the same, so there is no set time, and your answer time is just for us to refer to." ”

“OK!” Xiao Yao spread his hands and said.

"What is 3+8+4-5+2+4-1+7+2+6-4+2-6-8+4-2+5?" After asking, Sandra clicked the stopwatch on her phone's screen and started the timer.

"21!" Xiao Yao quickly gave an answer.

"Correct, next question!" Sandra reached out and clicked the stop button on the stopwatch, then immediately clicked the reset button.

"You don't seem to care much about your answering time?" After Sandra finished the operation, she didn't immediately come up with the next question, but looked at Xiao Yaodao.

She noticed that Xiao Yao didn't look down at the time display on his phone at all, and she didn't ask him how long it took.

"I seem to know why you are the one who tested me in this round of tests. Xiao Yao smiled, and some of the answers were not what he asked.

"Oh?" Sandra said with interest, looking at Xiao Yao, "Why?"

"Because you speak very fast!" Xiao Yao said with a smile, "So I think this round of testing is not only to test my mental arithmetic ability, but also to test my memory and mental quality." Compared to that, I don't think the time to answer the questions is important!"

Through the contact just now, Xiao Yao found that Sandra was the most outgoing of the four people and the fastest person to speak. And just now Sandra deliberately asked questions at such a fast pace, deliberately trying to create a tense atmosphere for Xiao Yao. In this case, let alone answering the question, whether or not you can remember the question will be a question.

"Well, you've found out!" Sandra smiled.

"But that doesn't mean the test is over, you pass the test. "Test continues!" Next question: Suppose you have three boxes in front of you, two of which are empty, and one of which has a piece of gold inside. The box has a lid, you can't see inside, you don't know which box has gold inside, but I know. Now, if you choose box number one, and I open box number three to show you, and you see that box number three is empty, will you change your choice?"

"I'll go! Isn't this the Monty Hall paradox of the previous life? The three-door problem is nothing more than replacing the door with a box, the car with gold, and the goat with nothing. Xiao Yao said in his heart.

"Change!" Without waiting for Sandra to press the stopwatch on her phone, Xiao Yao replied directly.

"Why?" asked Sandra, somewhat surprised. The others also looked surprised.

"After changing, the probability of getting the gold doubles!" Xiao Yao smiled helplessly, "Are you really taking a mental arithmetic test?"

Sandra was surprised and happy when she heard Xiao Yao's first half of the sentence, but when she heard the second half of Xiao Yao's sentence, she had some doubts in her heart, and said to Xiao Yao: "Of course, you are taking a mental arithmetic test! This is a requirement for you to calculate the profit probability of changing and not changing in your heart, although it is a little complicated, but it is indeed a topic that needs to be calculated." ”

"You're kidding me?" Xiao Yao said, "This is obviously Monty..."

When Xiao Yao said this, he suddenly remembered that there didn't seem to be Monty Hall in this world, so he changed his words and said: "This is obviously a topic extended from the paradox of Bertrand's box. Are you sure you're not testing my math knowledge?"

Sandra and the others were even more surprised when they heard Xiao Yao mention the "Bertrand Box Paradox".

"So you didn't calculate it, but the result of the Bertrand Box Paradox?" Sandra looked at Xiao Yao and said, "Do you know the Bertrand Box Paradox? Why? You said that you studied film and television school, and you don't study advanced mathematics!"

"The Bertrand box paradox is mentioned in the textbook of the probability course for science and engineering undergraduates at Huaxia University. Xiao Yao made up a reason, "Although I studied art and didn't study mathematics, I would double the books on this subject when I was fine." You know, I agreed with Yan a few years ago that I would go to the casino to play 21 points by counting cards. In my free time, I read books on probability. ”

"Well, it seems you've done a lot of preparation!" said Sandra, "but our topic still seems very different from Bertrand's box paradox, so how did you suddenly think of using Bertrand's box paradox to answer this question?"

"There's no why, I just thought of it!" Xiao Yao couldn't make it up, so he had to play tricks, "I feel that these two are the same problem! Maybe it's also talent?"
