**Michael**, Sunday, December 7, 2008 at 3:19pmwll...they need 2 things to happen to win

1) a blue marble from the first bucket (1 in 4 chance)

2) a red marble from the 2nd (1 in 3 chance)

so the chance for a win is (1/4) times (1/3) or (1/12)

if the game is played 36 times, then statistically 3 poeple should win

(36 X 1/12 = 3)

now if playyed 36 times the school will collect $36

if 3 won they will loose (3X$3 = $9)

so the net sum is 36-9 or $27
