Discrete Probability Distributions

A Tamiami shearing machine is producing 10 percent defective pieces, which is abnormally
high. The quality control engineer has been checking the output by almost continuous
sampling since the abnormal condition began. What is the probability that in a sample of
10 pieces:
a. Exactly 5 will be defective?
b. 5 or more will be defective?

________________________________________________________________

Suppose 1.5 percent of the antennas on new Nokia cell phones are defective. For a random
sample of 200 antennas, find the probability that:
a. None of the antennas is defective.
b. Three or more of the antennas are defective.
