Question 324286: A manufacturer of computer memory chips is know to produce defective memory chips with probability 0.10. The manufacturer packages the memory chips in bundles of 1000 chips. Suppose that 100 bundles are randomly chosen from the manufacturer's warehouse. What is the probability that exactly 5 out the 100 chosen bundles will each have exactly 100 defective chips?

You can put this solution on YOUR website! A manufacturer of computer memory chips is know to produce defective memory chips with probability 0.10.
The manufacturer packages the memory chips in bundles of 1000 chips.
Suppose that 100 bundles are randomly chosen from the manufacturer's warehouse. What is the probability that exactly 5 out the 100 chosen bundles will each have exactly 100 defective chips?
------------------------
Prob(a single package has 100 defective chips)
= binompdf(1000,0.1,100) = 0.0420
-----
P(5 of 100 will have exactly 100 defective chips)
= binompdf(100,0.0420,5) = 0.1670
=====================
