1)A popular television show recently had a 22% market share, which means that 22% were tuned to this show. Assume that an advertiser wants to verify that 22% share value by conducting its own survey with 10 households having TV sets in use at the time of the broadcast. What is the mean number of TV sets tuned into the show?

2)A TV show had a share of 20, meaning that among the TV sets in use, 20% were tuned to that show. Assuming that 5 households were surveyed, find the probability that none of the households are tuned to the TV show.
