In Problem, find the conditional probability that relays 1 and 2 are both closed given that a current flows from A to B.

Problem

The probability of the closing of the ith relay in the circuits shown in Figure is given by pi, i = 1, 2, 3, 4, 5. If all relays function independently, what is the probability that a current flows between A and B for the respective circuits?
