You are given a choice between two games, each with a $1 payout, which do you prefer? Game 1: you are given 4 roles of a single die, and you win if you roll at least one six. Game 2: you are given 24 roles of a pair of dice, and you win if you roll a pair of sixes at least once.
Attempt:
a) Game 1: $1-P(no six) = 1- (5/6)^4 = 0.5177469$
b) Game 2: P(single roll no pair six) = $1-1/36$
So 1- P(no pair six for 24 rolls) = $1- (1-1/36)^{24}$
