**Reiny**, Saturday, October 11, 2008 at 6:24pm1. 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
