The probability that the technical problem is solved can be defined as follows:
The probability that P solves the problem or probability that Q solves the problem or probability that both (P and Q) solve the problem
The probability that P solves the problem = 1/2
The probability that Q solves the problem= 1/4
The probability that both solve the problem = (1/2) x (1/4) = 1/8
The probability that the technical problem is solved =
