The television show September Road has been successful for many years. That show recently had a share of 21, meaning that among the TV sets in use, 21% were tuned to September Road. Assume that an advertiser wants to verify that 21% share value by conducting its own survey, and a pilot survey begins with 10 households have TV sets in use at the time of a September Road broadcast. Please show your answer to 4 decimal places. 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 21% share value is wrong? (Hint: Is the occurrence of at most one household tuned to September Road unusual?) yes, it is wrong no, it is not wrong
