3. (3 pts) A certain large shipment comes with a guarantee that it contains no more than 15% defective items. If the proportion of defective items in the shipment is greater than 15%, the shipment may be returned. You draw a random sample of 10 items. Let X be the number of defective items in the sample. If in fact 15% of the items in the shipment are defective (so that the shipment is good, but just barely), what is...

Suppose a shipment of 50 baseballs contains 3 that are defective. Baseballs from the shipment are randomly selected one at a time and checked for defects. If a baseball is found to be defective it is placed in a bin for return and reimbursement, if it is good it is put aside for use. Determine the probability that the 3th defective baseball is identified on the 10th sample.
