A recent poll indicated that about 83% of U.S. households had access to ahigh-speed Internet connection.

a. Suppose 100 households were randomly selected from the United States. How many of the households would you expect to have access to ahigh-speed Internetconnection?

b. If 20 households are selectedrandomly, what is the probability that exactly 14 havehigh-speed access?

c. If 20 households are selectedrandomly, what is the probability that 14 or fewer havehigh-speed access?
