Ten people visit a donut shop that sells the following donut flavors: Mint, Chocolate, Strawberry, and Sugar.
Jack is allergic to Sugar flavor while David, Brock and Charles are allergic to Strawberry flavor. How many different combinations of ten donuts can the group choose (with repetition)?
Hi guys, I have been struggling with this question for the past few hours and have still not been able to solve it. Could anyone help me out or suggest a solution? Thanks in advance!!
