1. the 3 seniors can be chosen i C(6,3) ways, which is 20
that leaves 2 juniors to be choses from the 4 juniors, which is 6
so the number of ways is 20x6 or 120 ways
2. there are 4 ways to get a 5, (1,4),(2,3),(3,2), and (4,1)
so prob of a 5 = 4/36 = 1/9
similarly there are 5 ways to get a 6.
so the prob of a 5 followed by a 6
= 1/9 x 5/36 = 5/324
3. correct
