Three persons work independently on a problem. If the respective probabilities that they will solve it are 1/3, 1/4 and 1/5, then find the probability that not can solve it.

Text Solution

AI Generated Solution

To find the probability that none of the three persons can solve the problem, we can follow these steps: ### Step 1: Identify the probabilities of each person solving the problem Let: - \( P(A) = \frac{1}{3} \) (Probability that person A solves the problem) - \( P(B) = \frac{1}{4} \) (Probability that person B solves the problem) - \( P(C) = \frac{1}{5} \) (Probability that person C solves the problem) ...
