Question

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 (asopposed 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 atthe franchise locations, and so on. Anita's reports that of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of customers at Anita's, exactly order their food to go?

Round response to at least three decimal places.

Answer

Answer 2

This is a binomial distribution:

p = .48, q = 1 - p = .52

The probability P{X} of exactly 4 customers from 5, will order food to go is:

P{X = 4} = (5 C 4)((.48)^4)((1 - .48)^1)
