You can put this solution on YOUR website! a football coach needs 12 players to ride on a float in a parade. he randomly selects names from a helmet. the helmet contains the names of 4 freshmen, 13 sophmores, 14 juniors, and 8 seniors. what is the probability the first two names chosen are seniors?
-----------
Number of ways to pick the 2 seniors: 8C2 = [8*7]/[1*2] = 28
Number of ways to pick any two from the group = 39C2 = 39*38/1*2 = 741
--------
Probability(1st two are seniors) = 28/741 = 0.037786...
