The television show Ghost Whistler has been successful for many years. That show recently had a share of 27, meaning that among the TV sets in use, 27% were tuned to Ghost Whistler. Assume that an advertiser wants to verify that 27% share value by conducting its own survey, and a pilot survey begins with 11 households have TV sets in use at the time of a Ghost Whistler broadcast. a) Find the probability that none of the households are tuned to Ghost Whistler. P(none) = Incorrect (round answer to 4 decimal places) b) Find the probability that at least one household is tuned to Ghost Whistler. P(at least one) = (round answer to 4 decimal places) c) Find the probability that at most one household is tuned to Ghost Whistler. P(at most one) = (round answer to 4 decimal places) d) If at most one household is tuned to Ghost Whistler, does it appear that the 27% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Ghost Whistler unusual?)

• yes, it is wrong
• no, it is not wrong
