An advertiser wants to verify that 30% share value by conducting its own survey, and a pilot survey begins with 15 households have TV sets in use at the time of aGreen's Anatomybroadcast.

Find the probability that none of the households are tuned toGreen's Anatomy.P(none) =

Find the probability that at least one household is tuned toGreen's Anatomy.P(at least one) =

Find the probability that at most one household is tuned toGreen's Anatomy.P(at most one) =

If at most one household is tuned toGreen's Anatomy, does it appear that the 30% share value is wrong? (Hint: Is the occurrence of at most one household tuned toGreen's Anatomyunusual?)

• No, it is not wrong
