The television show Ghost Whistler has been successful for many years. That show recently had a share of 24, which means, that among the TV sets in use, 24% were tuned to Ghost Whistler. An advertiser wants to verify that 24% share value by conducting its own survey, and a pilot survey begins with 13 households have TV sets in use at the time of a Ghost Whistler broadcast. Find the probability that none of the households are tuned to Ghost Whistler. P(none) = Find the probability that at least one household is tuned to Ghost Whistler. P(at least one) = Find the probability that at most one household is tuned to Ghost Whistler. P(at most one) = If at most one household is tuned to Ghost Whistler, does it appear that the 24% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Ghost Whistler unusual?)
