If you randomly touch two balls from a box containing five black balls and five red balls, according to Xiao Ming and Xiao Min's theory, will there be a difference between touching one ball at a time and touching two balls at a time? Joke! So Xiao Liang was right.
If Xiaoming meets Xiao Min first, Liang Xiao comes second and Liang Xiao comes third.
Xiao Ming's chance is naturally one-third, and the chance of not touching it is two-thirds.
If he doesn't touch it, the probability that Xiao Min will touch it from the remaining two pieces is 2/3*( 1/2)= 1/3.
Finally, it was left to Liang Xiao 1/3, so three people had equal opportunities.
