Suppose that ten items are chosen at random from a large batch delivered to a company. The manufacturer claims that just 3% of the items in the batch are defective. Assume that the batch is large enough so that even thought the selection is made without replacement, the number 0.03 can be used to appropriate the probability that any one of the ten items is defective. In addition, assume that because the items are chosen at random, the outcomes of the choices are mutually independent. Finally, assume that the manufacturer’s claim is correct.
To find out the probability that none of the ten is defective.
The manufacturer claims that just of the items are defective. Total ten items are chosen from a large batch.
According to the given information the following things can be written
To find out the probability that at least one of the ten is defective.
To find out the probability that exactly four of the ten is defective.
To find out the probability that at most two of the ten is defective.
