Question 1096953: A lot of 50 electrical components numbered 1-50 is drawn at
random, one by one, and is divided among five customers.
(a) Suppose that it is known that components 3, 18, 12, 26, and 46 are defective. What is the
probability that each customer will receive one defective component?
(b) What is the probability that one customer will have drawn five defective components?
(c) What is the probability that two customers will receive two defective components each,
two none and the other one?

A lot of 50 electrical components numbered 1-50 is drawn at
random, one by one, and is divided among five customers.
(a) Suppose that it is known that components 3, 18, 12, 26, and 46 are defective. What is the probability that each customer will receive one defective component?
Ans:: (5/50)(4/49)(3/48)(2/47)(1/46)
---------------------------------------------
(b) What is the probability that one customer will have drawn five defective components?
Ans: 1/(50C5)
-------------------------------------------
(c) What is the probability that two customers will receive two defective components each, two none and the other one?
Ans: (5C2/50C2)(3C2/48C2)(1/46)(45/45)
