Question
A bag contains 6 blue balls, 5 green balls and 7 yellow
balls. Two balls are drawn simultaneously. Find the probability that both the balls are of same colour.Solution
Total number of balls in the bag = 6 + 5 + 7 = 18 Total possible outcomes = 18C2 = 153 Number of favourable outcomes = 6C2 + 5C2 + 7C2 = 15 + 10 + 21 = 46 Required probability = 46/153
