The television show 50 Minutes has been successful for many years. That show recently had a share of 26, which means, that among the TV sets in use, 26% were tuned to 50 Minutes. An advertiser wants to verify that 26% 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 50 Minutes broadcast. Find the probability that none of the households are tuned to 50 Minutes. P(none) = Find the probability that at least one household is tuned to 50 Minutes. P(at least one) = Find the probability that at most one household is tuned to 50 Minutes. P(at most one) = If at most one household is tuned to 50 Minutes, does it appear that the 26% share value is wrong? (Hint: Is the occurrence of at most one household tuned to 50 Minutes unusual?) no, it is not wrong yes, it is wrong

Find the probability that none of the households are tuned to 50 Minutes.
P(none) =
Find the probability that at least one household is tuned to 50 Minutes.
P(at least one) =
Find the probability that at most one household is tuned to 50 Minutes.
P(at most one) =
If at most one household is tuned to 50 Minutes, does it appear that the 26% share value is wrong? (Hint: Is the occurrence of at most one household tuned to 50 Minutes unusual?)
- no, it is not wrong
- yes, it is wrong
