If I have 15 flavors of ice cream and 81 different toppings, how many different combinations could I create (assuming only 1 flavor of ice cream in the container at a time)?
I got 36267774588438900000000000 ???
IS THIS RIGHT???
Ms. Sue ???? i could have 0 toppings (that's 15).....or i could have 1 topping (x's 15 flavors) - that's 1215 ...or i could have 2 toppings 81x80(x's 15 flavors) that's 97200 more...
Don't i have to get the sum of all of the combinations ??
OK. I assumed only one flavor and one topping.
