Consider each of the 40 similar bets from 2 to 2^40. Suppose you could take them all at the same time in a mutually exclusive game, such that the chance of winning nothing is 1/2^40. For example, the game could be a sequential coin flip until the coin shows tails, and paying 2^n when the nth flip is the first one to show tails, and paying $0 if the all of the first 40 flips are heads.

Why would you not be willing to pay $40 to play this game?
