Your local grocery store just received a large shipment of apples, oranges, pears, and bananas---there are only 5 of each fruit. You are shopping at the store and will purchase your fruit for the week.
How many ways can you select $10$ pieces of fruit from your store's supply of apples, oranges, pears, and bananas, if you need at least $2$ oranges and $1$ apple?
I understand that there are 17 spots to choose from because 3 have been chosen and there are a total of 20 fruits. Would I use the combination by repetition formula? I can't quite wrap my head around what to do. Any help would be appreciated.
