#10 From a shipment of 65 transistors, 3 of which are defective, a sample of 4 transistors is selected at random.
(a) In how many different ways can the sample be selected?
In = = 788040 ways.
(b) How many samples contain exactly 3 defective transistors?
62 samples: To the subset of 3 defective samples, you can add ONE and ONLY ONE of the remaining 62 transistors.
(c) How many samples do not contain any defective transistors?
= = 557845 samples.
