Question

Of the automobiles produced at a particular plant, 40% had a certain defect. suppose a company purchases five of these cars. what is the expected value for the number of cars with defects?

Answer 1

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
