Best ResponseYou've already chosen the best response.0For example, "3 Choose 1" is the number of ways you can pick 1 thing from a group of 3 things. Suppose you had wanted to buy apples, oranges, bananas and you could only buy one of them. How many options do you have? You’d have 3. That’s “3 Choose 1”. What if you could buy two of them? How many ways are there to choose 2 fruits from 3? You can have apples and bananas, apples and oranges, or bananas and oranges. So “3 Choose 2” is 3.
