"Knock Knock Knock ......"

"Click" Yi Chen just opened the door early in the morning and saw Simple standing at the door of his house.

"Hey, morning," he said with a simple smile.

"Morning," Yi Chen nodded and replied.

"Huh...... What about them? Haven't arrived yet? Asked simply.

"Not yet," Yi Chen replied.

"Come in first," Yi Chen said.

"Okay"

After saying that, she walked in, and she found that Yi Chen's home was extraordinarily large, very retro, and a kind of literary style, and there were photos of some well-known scientists or painters hanging on the wall of the living room.

"Aren't your aunts and uncles at home?" Asked simply.

"They went out to do business, and I lived alone all year round." Yi Chen replied.

As he spoke, he poured a glass of water and handed it to Simple.

"Thank you," replied simply, taking the glass of water.

"You're welcome," Yi Chen replied.

"Am I coming too early to disturb you?" Asked briefly and cautiously.

"No," Yi Chen replied.

"Oh, that's good, you...... Have you eaten breakfast? Asked simply.

"Not yet, I'm used to not eating in the morning," Yi Chen continued to answer.

"How's that going to work? If you don't eat breakfast all year round, your stomach will be hungry, and people like me are the kind who don't eat a meal and die of hunger."

"Huh...... Where's your kitchen? Why don't I go and make porridge for you? Think of it as a mental damage fee that bothers you...... emm…… So to speak? He said simply and carefully.

"Okay, turn left and go straight to the kitchen, and the rice is in the white cabinet next to it," Yi Chen said.

"Okay, then I'll go" After saying that, he simply put down his schoolbag and went to the kitchen, found the rice according to the place Yi Chen said, washed the rice and boiled porridge......

Half an hour later----

"Whew~ The porridge is okay, do you want to drink something" said with a simple smile.

"Okay, thank you," Yi Chen picked up a bowl and put a scoop of porridge after speaking. Speaking of which, I came in a hurry in the morning, and I didn't eat anything at home, so I comforted myself at this time.

"You're welcome, hee-hee," he said with a simple smile. By the way, I also served a bowl of my own.

"Whew~" Yi Chen blew lightly, ate a spoonful, and found that he hadn't thought the porridge was so delicious before? Why is this porridge so delicious now?

"Knock Knock Knock ......"

There was a knock on the door......

"Oh? I arrived alone?? Shen Yu asked.

"And simplicity." Yi Chen replied.

"Just the two of you?" Shen Yu questioned.

"Hmm," Yi Chen said.

"Oh, a lonely man and a widow, in the same room, there is a situation...... Hehe......" Shen Yu smiled with a win-winning face.

"Okay, don't make trouble, good~ We're just drinking porridge," he said with a simple helpless smile.

"I'm going to drink it too, hehe......" Shen Yu said.

"Okay, I'll serve it to you," he said simply, walked to the kitchen, and brought another bowl of porridge.

"It's really fragrant~ Xiao Shan is really a typical good wife and mother~" Shen Yu said solemnly.

After a while, when everyone arrived, they drank a bowl of porridge by themselves, but fortunately, there was enough to boil.

"I'm going to wash the dishes," he said simply.

"Let's go with me, you all take out your homework and do it," Yi Chen replied.

"Okay then," he said simply.

"Little single~ I found out that I forgot one thing yesterday," Shen Yu said.

"What's the matter?" Ask simply.

"It's just that I said yesterday that I was going to buy a novel, but I ended up playing too much, and I forgot ......about it when I came back," Shen Yu covered her face and said.

"It seems to be yes...... Gu Xing said.

"Older people, the brain is not very good...... I recently had Alzheimer's disease......" Lin Xuan covered her face and smiled.

"Well, it depends on the fact that today's homework may be done...... If you can't finish it, you can't buy it," he said simply.

"I don't mind buying it for you," Gu Yiran said.

"Yes, I'm not here to really study anyway, I'm mainly here to accompany my daughter-in-law," Su Shuo continued.

"No, don't leave any of them, wait until the homework is finished," Yi Chen said coldly.

"Okay, okay, since Yi Dashen has spoken, we don't dare to disobey, after all, bothering others in other people's homes, Xiao Dandan, then you can accompany me next week" Shen Yu said.

"Okay," replied simply.

"Then let's start with math," Yi Chen said.

……

Yi Chen...... How to do this question? "Ask simply.

"What's the question?" Yi Chen asked.

"That's it." Simply bite the tip of the pen and point to it.

When Yi Chen leaned over and carefully explained the simple question......

His eyelashes are so long, thick and curly, with clear roots and clear pupils...... Thinking about it simply, he stared at Yi Chen's start......

"FY(y)=P(Y≤or equal to y)=P(X is greater than or equal to (3-y)/2)=1-P(X is less than or equal to (3-y)/2)...... f(y)=1/2f((y-3)/2), the result is certainly not negative, and E (XY=E(X)E(Y) can be deduced from X and Y independently of each other, but the inverse is not valid, and the nature of mathematical expectations in the probability theory book is clearly written, so D is wrong. Got it? Yi Chen asked.

"Ah......? Uh-huh...... Understand...... Understood" replied in a simple and embarrassing way.

"Okay, what's the answer to this question?" Yi Chen asked.

"Huh? Yes B ...... No, it's D......," he said simply uncertainly.

"It's A, it's all wrong with D, tell me about your ......" Yi Chen flicked his simple head lightly, shook his head helplessly and said.

"Huh? Oh......" said simply, shyly.

"Ahh......h I'm hungry......" Shen Yu said with a yawn.

"I'm hungry too......" Gu Xing said.

"And my ......," Lin Xuan said helplessly.

"There are a lot of sandwiches in the refrigerator, take them yourself," Yi Chen said.

After speaking, Mu Yiran and Su Shuo immediately rushed to the refrigerator, took out a large handful of sandwiches, and everyone ate them......

"It's delicious~" Shen Yu said.

"Yes, my brain is too tired in the morning, so I have to relax and relax......," Gu Xing said.

"You're still overtired, I think you've slept quite well all morning," Lin Xuan said solemnly.

"Oh, you can't see through it," Gu Xing said with a smile.

A beautiful day slipped away in the gap of time......

6 p.m. ----

"It's not early, I have to go home, my mother is still waiting for me to eat at home," Gu Xing said.

"I'll send you," Su Shuo said.

"Alright then, you guys go home first, be careful on the road and stay safe" said simply.

"Then I'll go back too~" Lin Xuan said.

"Anyway, I'm with Xuan Xuan," Mu Yiran said.

"Come on, you all go back, I have to leave with Simple, see you tomorrow" Shen Yu said disdainfully.

"See you tomorrow at school," everyone said and went home.

"I'll send you." Yi Chen said simply.

"Don't bother Yi Dashen, I'll be with us little alone," Shen Yu ran to the simple front and said to Yi Chen like an old chicken protecting her cubs.

"Yes, yes, it's okay to have Yuyu with me, we have to go, thank you for this day" said simply.

"Well, you're welcome, then...... Be careful on ...... road," Yi Chen said.

"Okay, see you tomorrow," replied simply.

"Well, goodbye......" Yi Chen said.
