A box containing 24 seemly identical resistors has just been received. However,unbeknownst, 4 of these resistors are defective.
a. Five resistors are randomly selected from this box without replacement (oncemoved from the box it is not returned to the box), what is the probability that oneor more of the defective resistors is among those selected?
b. Five resistors are randomly selected from this box with replacement (after theresistor is removed and checked, it is returned to the box prior to the nextselection (hence the same resistor can be selected more than once)), what is theprobability that one or more of the defective resistors is among those selected?
