Amazon keeps track of the frequency with which products are returned as defective. For one notoriously terrible company, Amazon has tracked that 30% of their products are returned as defective. This rate appears to be unchanging over time.
How many products, on average, will Amazon sell from this company until they sell a defective product? And what is the standard deviation of that number?
(A) H = 0. 30 products; o = 0.26 products
(B) M = 3 products; o = 3 products
(C) M = 3 products; o = 1.45 products
(D) M = 3. 33 products; o = 2.79 products
(E) H = 3. 33 products; o = 0.78 products
