The expected value for the number of cars with defects can
be obtained by multiplying the probability of success (i.e. the percentage of
products with defects - 40%) by the number of cases (i.e. the number of cars
purchased – 5).
40 / 100 X 5 = 2
Therefore, the expected value for the number of cars with
defects will be the percentage of products with defects is 2
