you guys have been such a big help lol. i have... i think just one maybe two more question that i need help with.
You play a coin toss game with your friend. The game is that you toss three coins. If ALL heads or ALL tails come up, your friend pays you 4$. If any other combination appears, you pay your friend 1.50$
a) show (using expectation) that this game is unfair.
b) to whom is this game unfair?
