Question
A basket contains ‘x’ red apples and 12 green
apples. If the probability of selecting a red apple is 2/5, then find the probability that two apples picked at random are of different colours.Solution
ATQ, Total = x + 12 So, x/(x + 12) = 2/5 Or, 5x = 2x + 24 So, x = 8 Desired Probability = (8C1 × 12C1)/(20C2) = (2 × 8 × 12)/(20 × 19) = 96/190 = 48/95
