#2 was correct, I just wanted to know what your were thinking
you are choosing 3 of the 5 toppings which is C(5,3) = 10

I’m doing this same problem but can’t figure how you came up with 10. Can you help
Me figure out how you solved it

The problem is a combination because the order doesn't matter so you have to use the formula nCr equal 5C3 = 10
