The sample of a random sample of moviegoers shows that 40% purchase popcorn to eat while watching the movie. If a theater has 80 people in it, how many people should you expect to have purchased popcorn?

Answer 1

You can find the expected number of people who purchased popcorn by multiplying the total number of people in the theater by the percentage of people who purchase popcorn:

Expected number of people who purchased popcorn = 80 x 0.40 = 32

Therefore, you should expect 32 people to have purchased popcorn.
