"Li Da was a good student. He likes cosplay, just like us. Sir, he's not a bad person," Wen Ziyu added.
Fang Zhen took the pill box and looked at the now docile Li Da. "You're a good student, huh? Then solve a problem for me."
"An opaque bag contains 5 red balls and 3 blue balls.
"Now, two balls are randomly drawn from the bag in succession, one at a time. The ball is replaced after each draw. Calculate the probability of drawing at least one red ball."
"Solve it. This is from the probability section of high school math. It's not difficult. I want the answer within three minutes."
"Huh?" Li Da was stunned. He never expected to be coerced into solving a math problem.
Fang Zhen glared at Li Da.
"I'll do it, I'll do it... This is just my unlucky day." Li Da, looking aggrieved, lowered his head and started muttering. It was hard to tell if he was doing mental calculations or just grumbling to himself.
