1. A red die and a blue die are tossed. What is the probability that the red die shows an odd number and the blue die shows a 1 or 2?
---
P(red odd) = 3/6 = 1/2
P(blue 1 or 2) = 2/6 = 1/3
--
P(red odd AND blue 1or 2) = (1/2)(1/3) = 1/6
------------------------------------------------------------------------
2. From a group of 6 men and 4 women, a committee of 3 is to be selected at random. Find P(at least 2 women).
P(2 or 3 women) = P(2 women/1 man) + P(3 women/0 men)
But P(2 women and 1 man) = [4C2*6C1/10C3] = [6*6/120] = 3/10
And P(3 women/0 men) = 4C3/10C3 = 4/120 = 1/30
Therefore, Answer = (3/10) + (1/30) = 1/3
