The wheeling tire company produces a batch of 5000 tires that includes exactly 200 that are defective.
a. if 4 tires are randomly selected for installation on a car, what is the probability that they are all good?
-------
P(defective) = 200/5000 = 1/25 = 0.04
P(good) = 0.96
---------------------
P(4 good) = 0.96^4 = 0.8493
=====================================
b. If 100 tires are randomly selected for shipment to an outlet, what is the probability that they are all good?
P(100 good) = 0.96^100 = 0.0169
-------------------------------------
Should this outlet plan to deal with defective tires returned by consumers?
I'll leave that to you.
Cheers,
Stan H.
