Question 1178340: The event A1 that a certain part of an airplane works during a flight is determined to be 0.99 .Sine the engineers are reluctant to risk the probability 0.01 of failure they insert another pare in parallel. This means the failure occurs if and only if both parts fail. Let the event A2 stand for the success of the second part. Assume that it has been determined that P ( A2 ) = 0.99 and that A1 and A2 are independent events. Find the probability of success.
You can put this solution on YOUR website! probability of no success is when both parts fail and that is 0.01^2 or 0.0001
so the probability of success is 1-0.0001=0.9999
