wll...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
Ok I get it now!!!! Thank you so much!
