005 I would like to be single for another ten years

Xu Mo looked at Ning Wei proudly.

That's right, she's in Kauningwei.

It’s not that Ning Wei did something wrong, but that Xu Ruixuan is not honest!

In fact, there is another version of the whole thing, just to take care of Xu Ruixuan's face, the two girls didn't say it.

There were actually only three people in the first meeting.

Xu Mo pulled his best friend to study with Xu Ruixuan in the general guide, and soon discovered that this was a parallel product.

Xu Ruixuan can only admit that some of his problems were discussed with other classmates...

Everyone made an appointment to meet the classmate who is good at math the next day.

After Xu Ruixuan returned to the dormitory, he thought about it carefully for a long time and felt that he still couldn't take Ning Wei to meet Xu Mo.

If anyone in the dormitory threatens him in terms of appearance, then it is only Ning Wei.

Tall and thin, pretty, and have good grades...

Before he could confirm his relationship with Xu Mo, Xu Ruixuan felt that he could not let Ning Wei take action directly.

Although everyone in the dormitory has a good relationship, who hasn’t had a little selfish desire when it comes to future happiness?

So he called Liu Cong.

Who made Liu Cong, nicknamed Fat Wolf, the fattest one in Quandai? And there were many acne on his face.

No matter what, Liu Cong's grades are better than him. Maybe he will get over it?

Unfortunately, they failed again...

That's why this meeting was made.

Ning Wei's performance now seems to be a possibility of being a parallel product.

After all, the question is so long, don’t you have to look at it for several minutes?

She didn't know that Ning was so shocked that she was so shocked that she could not be more.

If Ning Wei was not sure if there was any change in his body when he was in the dormitory, then he was now sure that there was a high probability that there was something wrong with his brain.

There is a saying that geniuses and lunatics are often only a line away.

Ning Wei felt that he should be going crazy.

...

"Are you thinking?"

Xu Mo's problem is Ning Wei awakening from his own world.

First, he looked up and glanced at Xu Ruixuan who was winking at him, and then nodded at the girl opposite him.

"It's solved."

"ah?"

Xu Mo was stunned for a moment, obviously not expecting that Ning Wei would actually say this. How could he explain it? I calculated it silently in my heart?

"First prove a. Here we have to divide it into two steps. First prove it is a Markov process, and then prove it is a homogeneous Markov process."

"Because a machine tool that is working at time t has the probability of stopping working at time t+△t is μ△t+O(△t); a machine tool that does not work at time t has the probability of starting working at time t+△t is λ△t+O(△t); these results are not related to the previous t and are only related to △t. The question has already shown that the machine tool's working condition is independent, so it can be seen that this is a Markov process."

"The next step is the second step. It can be deduced from the conditions: Pij(△t)=P{X(t+△t)=j | X(t)=i}"

"From this we can find: (N-i)λ△t+O(△t), j=i+1, which means that the N-i unit was broken, and another unit was improved;"

"iμ△t+O(△t),j=i-1, that is, a good i-taichung broke one;"

"1-(N-i)λ△t-iμ△t+O(△t),i=j, that is, one good or one bad, one bad or one bad;"

"O(△t),|i-j |>1, that is, it is impossible for both good and bad to exist at the same time."

"It can be seen that the transfer probability from t to t+△t is only related to △t and has nothing to do with t, so this Markov chain process is homogeneous."

"Then the second question, find the stationary distribution, we can see from the above conditions..."

In order to get into the problem-solving state, my pen began to write and draw on paper.

In fact, Ning Wei is not very good at explaining questions, but he has the most detailed problem-solving process in his mind, so he just needs to copy out the things in his brain step by step and it’s almost done.

As for whether the beauty next to me can understand, Ning Wei actually doesn't care much.

"From the above inference, we can conclude that at most three units are not working}=P{7≤X(t)≤10}=P7+P8+P9+P10=0.599."

"That is, when N=10, λ=60, μ=30, the probability that at most three units will not operate in a stationary state is 0.599."

...

Xu Mo took the manuscript paper that Ning Wei answered with a blank look on his face, and handed it to his best friend.

Ning Wei was very attentive when solving the problem, so he didn't notice that when he started to solve the problem, Yang Xiaohui glanced at him from time to time.

Yang Xiaohui took the manuscript for answering the question, then opened the book she was flipping, turned to the end, and after careful comparison for a few minutes, she said: "It's all right, and the problem-solving process is more detailed than the reference answers in the book."

"Haha, I just said that the talented people are in our dormitory. Hey, it's not that I don't want to bring Ning Wei out. This guy is very obedient and has to go to self-study with his girlfriend every day. If you can pull him out today, you have to thank his girlfriend for giving him a vacation!"

Xu Ruixuan winked at Ning Wei.

Ning Wei finally figured out why he had a girlfriend today.

I couldn't help but laugh and then remained silent.

Well, it seems that Xu Ruixuan really likes this Xu Mo.

What he didn't know was that Luo Xiang actually wanted to speak up for justice, but when he was solving the problem, Xu Ruixuan handed Luo Xiang a note and promised a week of meals, Luo Xiang betrayed.

Fortunately, Ning Wei had no plans to fall in love at this time.

If possible, he was even willing to continue to be single for ten years in exchange for himself to figure out what was going on with him today!

Anyway, I have been single for twenty-two years, and I will be single for ten years.

He hasn't had enough money to have a dull love relationship with him recently.

Of course, it is better to be willing to let go of the benefits you should not let go of.

"Well, Mr. Xuan, did you promise to invite me to mix barbecue with my girlfriend Qijiu and eat for one day count?" Ning Wei asked at the roommate opposite.

"Well, count, must count."

"But she said she wouldn't eat barbecue if she wanted to lose weight recently. It would be better to convert it into treating me to a week's meal."

"Of course it's okay!"

When Ning Wei wanted to say something, the phone started to vibrate.

Ning Wei picked up the phone, smiled embarrassedly at the girl beside her, and then picked up the phone and went to the corridor.

"His girlfriend?" Xu Mo asked Xu Ruixuan.

"Maybe?"

"You girls in the Mathematics Academy are really strict in keeping your boyfriend!"

"Haha, average!"

Yang Xiaohui, who was next to her, turned her head curiously again and glanced at Ning Wei who had left.

These guys seem a bit strange.

...

The phone call was called by the instructor.

"Hey, where are you now?"

"Study in the general map."

"Oh, if you have time, come to my office now."

"Okay, I'll arrive in about ten minutes."

"Okay, don't worry, I'll wait for you."

...

Back at the tables where the two dormitories studied, Ning said apologetically: "Sorry, I have something to do, I have to leave first. You can study for yourself first, see you next time."

"Is it really a girlfriend looking for?" Xu Mo asked.

"Haha..." Ning Wei laughed dryly, without explaining.

"Oh, I'm just in the mood for something, so I have to go back to the dormitory and go together." Luo Xiang, who could no longer sit still, said.
Chapter completed!
