A problem is given to three persons P, Q, R whose respective chances of solving it are 2/7, 4/7, 4/9 respectively. What is the probability that the problem is solved? A. 112/147 B. 162/147 C. 132/147 D. 122/147 Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation Probability of the problem getting solved = 1 – (Probability of none of them solving the problem) Probability of problem getting solved = 1 – (5/7) x (3/7) x (5/9) = (122/147) Workspace
