You can put this solution on YOUR website! in a community newspaper the weekend events advertised are two plays, five movies, and three baseball games. a couple has decided to attend four activities. find the probability that they choose to attend two baseball games, one movie, and one play.
----
# of ways to choose 2 baseball, 1 play, 1 movie:: 3C2*2C1*5C1 = 3*2*5= 30 ways
----
# of ways to make 3 choices randomly:: 10C3 = (10*9*8)/(1*2*3) = 120 ways
---
P(2 base and 1 play and 1 movie) = 30/120 = 1/4
----------------
Cheers,
