(a) How many different samples of size 10 are there that contain at least three defective parts? (b) How many ways to obtain a sample of 10 parts from the bin of 50? (c) What is the probability of obtaining at least three defectives in a sample of 10 parts?

A batch of n = 50 items contains m = 10 defective items. Suppose k = 10 items are selected at random and tested. How many items, k, do we need to sample, in order to get at least one defective item, with probability greater than 0.5?
You are dealt two cards successively (without replacement) from a shuffles deck of 52 playing cards. Find the probability that the first card is king and the second card is queen. 7. An IRS auditor randomly selects 3 tax returns from 58 tax returns of which 8 contain errors. What is the probability that she selects none of those containing errors? 8. 9. A sample of 4 different calculators is randomly selected from a group containing 47 that are defective...
Judy Holmes Industries has decided to use a p-Chart to monitor the proportion of defective castings produced by their production process. The control limits on these charts will be designed to include 95%95% of the sample proportions when the process is In Control. The operations manager randomly samples 400400 castings at 1616 successively selected time periods and counts the number of defective castings in the sample.
