The Party of NonvotersFrom past elections, nonvoters are those who are either not registered to vote or are considered unlikely to vote in an upcoming election. Nonvoters are very different demographically from likely voters.

Roughly a third (34%) of nonvoters are younger than 30 and most (70%) are under 50; among likely voters, just 10% are younger than 30 and only 39% are under 50 (Source: Pew Research Center, October, 2014,"The Party of Nonvoters"). Suppose you interview 9 people who are considered nonvoters.Round answers to 4 decimal places.

a.) What is the probability that 9 of the nonvoters are younger than 30?

b.) What is the probability that more than 2 of the nonvoters are younger than 30?

c.) What is the probability that at least 2 of the nonvoters are younger than 50?

d.) What is the probability that fewer than 9 of the nonvoters are younger than 50?
