I vaguely remember my combination and permutation math from many years ago. I have a real-world problem to solve which can be simplified as follows. Lets say I have 5 different types of fruits and I can combine them into a fruit salad using 1 or more combinations, e.g.:
apples
apples + oranges
apples + grapes
apples + oranges + grapes
oranges + grapes
...
How many different combinations will I have in total? Order is irrelevant.
apples
apples + oranges
apples + grapes
apples + oranges + grapes
