Zheng Jie was a bit curious, "Hey, is the game just starting?"
"But hasn't the fundamental principle and logic of this game already been revealed?"
Clearly, what Yang Yuting was talking about, this 'wallet game,' or 'two-envelope paradox,' its principle is not complex.
Simply put, it's about two slips of paper with different amounts written on them, one being ten times the amount of the other, and the question of whether to switch after drawing one.
If there's an error in calculating expected returns, it would lead to the wrong conclusion of 'no matter how you switch, it's a positive return.'
But upon digging deeper, it just goes back to the original point where it doesn't matter whether you switch or not.
It's merely a 50% chance to switch from a small envelope to a large envelope, or a 50% chance to switch from a large envelope to a small envelope.
