Two boys are bored, so they decide to play a coin game. They will alternate turns flipping a coin. The first one to land it on heads has to pay the other $5 dollars. The 2nd boy, being a gentleman, gives the 1st boy a decision, to go first or second. Which has the better chance, going 1st or 2nd, of landing heads first and how?

Spoiler for dont be a gentleman
