Forty-nine percent of US teens have heard of a fax machine, then the probability that the teen has heard of a tax machine is p=0.49 and the probability that the tenn hasn't heard of a tax machine is q=1-p=1-0.49=0.51.
Use binomial distribution.
The probability that among 12 randomly selected teens exactly 6 have heard of a fax machine is
