At coldstone, you can have 1 ice cream flavor, 1 mix in and one topping for 5.50. If you have 12 ice cream flavors, 22 mix ins, and 3 toppings, how many different sundays can you get? im guessing its a combination..

What does "one topping for 5.50" mean ??

OpenStudy (anonymous):

wuld it be: 12C1 x 22C1 x 3C1/ all over wat?

OpenStudy (anonymous):

any1?

OpenStudy (inkyvoyd):

You want (12*22*3)/(3!)

OpenStudy (anonymous):

so 3 C1 in the bottom?

OpenStudy (inkyvoyd):

Yes, because the order doesn't matter

OpenStudy (inkyvoyd):

flavor-mix in-topping is the same as mix in- topping - flavor, actually there are a total of 6 of these, because theres 3*2*1 orders that don't matter. We divide by these 6, or 3!
