Answered by Anonymous
it's C
you set it up like this (say you have 3 toppings for your pizza and 6 toppings to choose from)
6
6C3 = ----
3
then.. = 6 times 5
---------
3 times 2
when you multiply the numbers they go lower and lower until it reaches the number (aka the 3 toppings for your pizza) .. kinda hard to explain.. sorry.

then you go 6 times 5 times 4
---------------
3 times 2 times 1

this then equals 120/6
120/6 = 20

im so sorry this is so hard to explain. I would have to visually (like on a paper and stuff) show you but I can't.
but its 20
