1. The problem statement, all variables and given/known data From a group of 3 freshman, 4 sophomores, 4 juniors, and 3 seniors, a committee of size 4 is randomly selected. Find the probability that the committee will consist of: a) 1 from each class b) 2 sophomores and 2 juniors c) only sophomores and juniors 2. Relevant equations How do you write "x choose n" in latex? For now I'll write (xCn) 3. The attempt at a solution I figured there (14C4) different committees, giving 1001 committees. a) [(3C1)(4C1)(4C1)(3C1)]/1001 = 144/1001 b) [(4C2)(4C2)]/1001 = 36/1001 c) 2/1001 Is this correct?
