Question
A basket contains 8 pink, 12 violet, and 5 indigo balls.
If 2 balls are picked at random without replacement, find the probability that the first ball is pink and the second ball is either violet or indigo.Solution
ATQ, Total number of balls = 8 + 12 + 5 = 25 Case I: First ball is pink and the second ball is violet. Probability = (8/25) × (12/24) = 8/50 = 4/25 Case II: First ball is pink and the second ball is indigo. Probability = (8/25) × (5/24) = 40/600 = 1/15 Required probability = (4/25) + (1/15) = 19/75
