The television show September Road has been successful for many years. That show recently had a share of 24, meaning that among the TV sets in use, 24% were tuned to September Road. Assume that an advertiser wants to verify that 24% 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 September Road broadcast.
A) Find the probability that none of the households are tuned to September Road.
B) Find the probability that at least one household is tuned to September Road.
C) Find the probability that at most one household is tuned to September Road.
D) If at most one household is tuned to September Road, does it appear that the 23% share value is wrong? (Hint: Is the occurrence of at most one household tuned to September Road unusual?)
O no, it is not wrong
