A bag contains 3 white, 4 black and 2 red balls. If 2 balls are drawn at random, then the probability that both the balls are white is
Total number of equally likely cases = 9C2 [ total no. of ball = 3 + 4 + 2 = 9 and 2 are drawn]
Total number of equally likely cases
= 9C2
9 × 8 1 × 2 = 36
Favorable cases = 3C2 = 3
[ No. of white balls = 3 and 2 are to be chosen]
Required probability = 3 36 = 1 12
