Sophia, Gabriel and Elizabeth take their driving test. The chances that they pass are 1/2
,
5/8
and 3/4
respectively.
(a) Find the probability that Sophia passes and the other two fail.
(b) By listing the possible outcomes for one of the girls passing and the other two failing,
find the probability that exactly one of the three passes.
(c) If only one of them passes, find the probability that it is Gabriel.
