each with 3 choices. Only one choice is correct per question. If Anna guesses on all questions, what is the probability that she gets exactly 3 correct?Solution
ATQ, Probability of a correct guess = 1/3 Probability of an incorrect guess = 2/3 Number of ways to choose 3 correct answers out of 6 = (6/3) = 20 So, the required probability = 20 × (1/3)3 × (2/3)3 = (20×1×8)/(27×27) = 160/729
