3 persons A, B, C work independently on a problem. The probabilities of them for solving the problem
are 1/3, 1/4, and 1/5 respectively. What is the probability that none of them can solve the problem is?​

Answer 1

Answer:

2/5

Step-by-step explanation:

Required probability = (1 - 1/3)(1 - 1/4)(1 - 1/5)

                                   = 2/3 x 3/4 x 4/5

                                    = 2/5
