A satellite can fail for many possible reasons, two of which are computer failure
and engine failure. For a given mission, it is known that:
The probability of engine failure is 0.008.
The probability of computer failure is 0.001.
Given engine failure, the probability of satellite failure is 0.98.
Given computer failure, the probability of satellite failure is 0.45.
Given any other component failure, the probability of satellite failure is zero.

(a) Determine the probability that a satellite fails.  = 0.00829
(b) Determine the probability that a satellite fails and is due to engine
failure.  =0.00784
(c) Assume that engines in different satellites perform independently. Given a
satellite has failed as a result of engine failure, what is the probability that
the same will happen to another satellite?


最后一个问题  为什么和A是一样而不是B呢？
