Atotal of 60% of the customers of a fast food chain order a hamburger, french fries, and a drink. if a random sample of 15 cash register receipts is selected, what is the probability that 10 or more will show that the above three food items were ordered?

This is called a binomial probability experiment. 

Let n = 15.

Let p = 0.6

The binomial distribution formula is represented by:

p = (n r)  

After plugging p and n into our distribution, we have 0.403. This means that the probability that 10 or more will show that the above three food items were ordered.
