**Reiny**, Sunday, March 7, 2010 at 8:51pmProb (HHH) = 1/8

expected value = (1/8)(15) = 1.875

prob(HHT or HTH or THH) 3/8

expected winnings = (3/8)(5) = 1 .875

prob(HTT or THT or TTH) = 3/8

expected winnings = (3/8)(2) = .75

prob( TTT) = 1/8

expected winning = 0

total expected winnings = 4.5

to play the game costs $4

expected winnings = $0.50

Bet you won't see that game in Vegas.
