Binomial problems: Basic

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the

proportion of its customers who decide to eat in the restaurant (as opposed to ordering the

food "to go"), so it can make decisions regarding the possible construction of in-store play

areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita's

reports that 48% of its customers order their food to go. If this proportion is correct, what

is the probability that, in a random sample of 4 customers at Anita's, exactly 3 order their

food to go?
