I started a senior citizen university after being unemployed, and I became the favorite of my uncles

Today's activity for Aunt Xu, Aunt Zhong and the other two girlfriends is to go to the video game arcade.

This idea was first proposed by Aunt Wen. She has been coming to the arcade with Uncle Fan to play the dance machine recently, and Aunt Xu and the others also wanted to try it.

Originally, the five of them had agreed to come together, but Aunt Wen said she had something urgent to do, so only the four of them came today.

When the idea was proposed, I felt it was novel, and when I stood at the door I was a little afraid to go in.

"Why don't we go to another place? This place is full of young people playing." Aunt Zhong looked at the busy video game arcade and felt like backing out.

"Since we're here, let's go in and try. There's nothing stopping us from playing." Aunt Xu took a step forward and turned around to ask, "You want me to lead you?"

"Let's go in together." Aunt Liang pulled Aunt Du and Aunt Zhong together and followed Aunt Xu's pace.

……

It was their first time in the arcade and they had only heard of many of the games but had never seen them.

The aunts were a little confused.

It was Aunt Du who stood up and said, "I watched the video in advance and know a little bit."

"They want to buy game coins for this."

"For some games, such as catching dolls, you just put in coins and if you catch them, you get something real."

"Some people have lottery tickets after winning, and the lottery tickets can be redeemed for prizes."

"So what should we do first?" Aunt Zhong asked.

"Of course I'll buy game coins first." Aunt Xu took photos everywhere curiously.

They bought a basket of game coins and decided to go to the popular project of catching dolls first.

When it comes to playing games, several people have very distinct characteristics.

They picked a claw machine filled with teddy bear dolls of various colors.

Aunt Zhong is a practical person, so she just took the game coins and started.

Aunt Liang was more cautious and chose to observe other people's actions first.

Aunt Du is a technical person, she is using search engines to look for tips on catching dolls.

Aunt Xu wanted to take good photos more than catching the dolls.

After Aunt Zhong inserted the coins, the others stared at the claw machine without blinking.

The clamps moved slowly with the operation of the joystick, and the aunts held their breath and slowed down their breathing.

"Am I in the right position?" It was Aunt Zhong's first time playing and she wasn't sure of the direction.

"Move to the left."

"A little further back."

"Okay, don't move, right here."

Aunt Zhong put her hands on the joystick and dared not move. "What are you going to do next?"

"Do you want to press this button?" Aunt Xu pressed the white button that was flashing colorful light.

The claw suddenly fell down, and when it was close to the bear's ear, it paused and then retracted.

"Oops, I almost caught it."

"Come on, come on, you guys try it too." Aunt Zhong got another game coin and joined the battle again.

The other three aunts each took a coin and tried their favorite claw machines.

"Hey, I caught it, why did it fall down again?!"

As Aunt Zhong complained, several aunts used up their coins almost at the same time, but still got nothing.

"I feel like it depends on luck. I'll try something else." Aunt Du took the game coins and went to look for the shooting game she saw as soon as she entered the door.

Aunt Du is an old player of a shooting game.

I also took a minor in shooter in the e-sports class, so shooting became a piece of cake for me.

This is a panoramic simulation gun game where you really have to aim at the target outside the glass with a gun.

The gun has a scope and a trigger. Aunt Du quickly became familiar with the operation. As long as she aimed, it would either hit the eight or nine rings.

It attracted a crowd of onlookers.

Several young people were eager to try: "Auntie, I want to learn!"

Aunt Du calmly put away the gun and taught them some techniques.

The arcade was very lively, with screams and singing everywhere.

Especially near the karaoke room where Aunt Xu went.

She came to the arcade not to play games, but to find a KTV to sing.

This is a small KTV, with one room per person.

Aunt Xu was determined to sing her playlist from beginning to end.

Only Aunt Zhong was still obsessed with the claw machine. She had already put in nearly 20 coins but still didn't catch anything.

She changed several machines unwillingly, and became more and more annoyed the more she played.

Aunt Liang took a fancy to a ball-dropping game machine in the distance.

Every time you press the button, a ball will fall. There are several grooves underneath, and the balls will roll randomly. When two balls overlap in the same groove, the game is over. It seems to be a test of luck.

After Aunt Liang listened to the person next to her explain the rules of the game, she sat down and started playing.

She is a very patient person and always presses the button neither too hard nor too lightly, but the ball is particularly disobedient and never lands where she wants it.

After playing a few times, the good-tempered Aunt Liang became a little anxious.

"My luck is so bad." Aunt Liang whispered.

"It has nothing to do with luck. It has to do with the machine settings and probability theory."

"You can think of it as being governed by a mathematical formula."

Aunt Liang thought the voice sounded very familiar and turned around to find it was Uncle Fan.

"Why are you here? Where's Xiao Wen?"

Xiao Wen is Aunt Wen. They often play together. Aunt Liang and Aunt Du are a few years older than them. They call Aunt Zhong Xiao Zhong and Aunt Xu Xiao Xu.

"She's here too. Let me tell you the formula first."

“This may seem like luck, but it’s actually a binomial distribution.”

"I'll calculate the probability of the ball landing at the specified location you want it to land at. Wait for me to write a formula."

Uncle Fan took out the small notebook he carried with him and wanted to teach Aunt Liang the binomial distribution.

A group of people walked past them.

"I heard there was a battle over there at the dance machine?"

"I saw her. She is a very elegant aunt."

Aunt Liang watched Uncle Fan, who was obsessed with explaining mathematical formulas, quietly put away his book, and said, "So the thing you and Xiao Wen were talking about was coming to the arcade to play the dance machine?"

"I... I'll go over and take a look. I'm leaving first." Uncle Fan, who was guessed, ran away quickly.

Aunt Liang put away the remaining game coins and sighed, "What happened today? Did the senior citizen university come to the arcade for team building?"
