The television show September Road has been successful for many years. That show recently had a share of 16, which means, that among the TV sets in use, 16% were tuned to September Road. An advertiser wants to verify that 16% share value by conducting its own survey, and a pilot survey begins with 15 households have TV sets in use at the time of a September Road broadcast. Find the probability that none of the households are tuned to September Road.
P(none) =

Find the probability that at least one household is tuned to September Road.
P(at least one) =

Find the probability that at most one household is tuned to September Road.
P(at most one) =

If at most one household is tuned to September Road, does it appear that the 16% share value is wrong? (Hint: Is the occurrence of at most one household tuned to September Road unusual?)
