How Can I Help? Are you helping to save the environment? A USA Today Snapshot found that about 78% of Americans believe that recycling trash makes the biggest difference in protecting the environment.

Suppose a random sample of n = 50 adults are polled and asked if they believed that recycling made the biggest difference in protecting our environment. Let us assume that the 78% figure is, in fact, correct. What are the probabilities for the following events?

a. Fewer than 30 individuals believe that recycling makes the biggest difference?

b. More than 40 individuals believe that recycling makes the biggest difference?

c. More than 10 individuals believe that recycling does not make the biggest difference?
