What on earth was going on?
They were all too stunned to speak.
"It's simple. This is a question of probability," Du Yu said with a smile. "This ugly gentleman just said that if he played enough rounds with me, he could bankrupt me. That's impossible."
Xie Bi'an froze. "Who are you calling ugly...?"
"The more rounds you play, the greater your chances of losing," Du Yu said slowly.
"But why...?" None of them really understood.
"There are twenty-four stones in total, in three colors, with eight of each color. If someone randomly draws twelve, there are 2,704,156 possible combinations. The 'eight-four-zero' combination that earns the player a hundred copper coins accounts for only 420 possibilities, while the 'five-four-three' combination that pays the stall ten copper coins accounts for 1,317,120. Do you understand now?"
Almost in unison, they said, "No..."
"Simply put, the chance of drawing 'eight-four-zero' is 0.02%, while the chance of drawing 'five-four-three' is 48.17%. According to probability theory, a player loses an average of 4.87 copper coins each round. Do you understand now?"

Striking while the iron was hot, Du Yu took the wooden sign and cloth bag and led everyone outside. He had intended to leave the
