Question
John is answering a survey with 3 questions, each with 2
options. Only one option is correct per question. If John answers randomly, what is the probability that he gets exactly 1 question right?Solution
ATQ, Probability of choosing the right answer = 1/2 Probability of choosing the wrong answer = 1/2 Number of ways to choose 1 correct answer out of 3 = (3/1) = 3 So, the required probability = 3 × (1/2)1 × (1/2)2 = (3×1×1)/(2×2×2) = 3/8
