Percents - Do want fries with that?

Yesterday, at Burger King where Dominique works, 60% of the customers ordered a burger. Show all work.



a. If 42% of the customers ordered a burger and fries, what is the probability that a customer who ordered a burger also ordered fries?



b. If 15% of the customers ordered a burger and onion rings, what is the probability that a customer ordered onion rings given that he/she ordered a burger?



c. If 36% of the customers ordered a burger and milkshake, what is the probability that a customer who ordered a burger also ordered a milkshake?
