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...
Twelve items are to be randomly selected from the first 100 items on an assembly line to determine the defect rate. How many different samples of 12 items can bechosen?
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. Table Control Chart Copy Table Step 8 of 8 : You, acting as the...
1. Daily production produces 50,000 balloons. It is known that theproduction process produces 0.004% defective balloons (i.e., the probability that a randomly selected balloon is defective is 0.00004). Whether one balloon is defective or not is independent of all other balloons. From one day’s production, estimate the chance of producing at least 3 defective balloons. 2. A shipment contains 100 I-Pods, 8 of which are defective. I sample 4I-Pods from the shipment of 100 I-Pods at random. Estimate the chance of...
