You can put this solution on YOUR website! A cruise director schedules 4 different movies, 2 bridge games, and 3 tennis games for a two-day period. If a couple selects 3 activities, find the probability that 1 of each will be selected.
----
# of ways to get 1 of each:: 4*2*3 = 24
# of sets of 3:: 9C3 = (9*8*7)/(1*2*3) = 84
----
P(1 of each) = 24/84 = 2/7
