There are six seniors four juniors and two sophomores. If a committee of three is to formed, find the probability that one of each will be selected.
------
# of ways to get one of each: 6*4*2 = 48
---
# of possible groups of 3 students: 12C3 = (12*11*10)/(1*2*3) = 220
----
Ans: Probability = 48/220
