The event A1 that a certain part of aeroplane works during flight is determined to be 0.99. sine the engineers are reluctant to risk the probability of 0.01 of failure they insert another part in parallel. This means the failure occurs if and only if both part fail. Let The event A2. to stand for the success of the second part. Assume That it has been determined that P(A2) is equal to 0.99 and that A1 and A2 are independent events. Find the Probability of success
