A company has determined that 1% of the parts it makes are defective. If the company packs a shipment of 5 parts to a customer, what is the probability that:         (a) none are defective                         (b)   more than 2 are defective.

Solution

Let X be the no of defectives.

X is binomial with p = 0.01 and n = 5

a) P(X=0) =0.9510

b) P(X>2) =9.851x10^-6
