The television show Pretty Betty has been successful for many years. That show recently had a share of 20 , which means, that among the TV sets in use, 20% were tuned to Pretty Betty. An advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 14 households have TV sets in use at the time of a Pretty Betty broadcast. Find the probability that none of the households are tuned to Pretty Betty. P( none )= Find the probability that at least one household is tuned to Pretty Betty. P( at least one )= Find the probability that at most one household is tuned to Pretty Betty. P( at most one )= If at most one household is tuned to Pretty Betty, does it appear that the 20% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Pretty Betty unusual?) no, it is not wrong yes, it is wrong.
