8- Suppose three coins are tossed and the number of heads is recorded . and the
sample space is S={0, 1, 2 , 3 } . find the probability space.
4 Suppose a student is selected at random from 100 students where 30 are taking
mathematics , 20 are taking chemistry , and 10 are taking mathematics and
chemistry. Find the probability p that the student is taking mathematics or chemistry.
(5 the probability that A hits a target is 4, and the probability that B hits the target
is 2/5 both shoot at the target. find the probability that at least hits the target.
