Hi guys again! I need help with this problem:

Berry Kold Creamery has four flavors of ice cream: vanilla, pistachio,black walnut, and strawberry.The daily sundae has three scoops of ice cream. How many variations of the sundae are there?

I don't need the numerical answer, I would just like how you would set the combination for the question to solve it.

Thanks!*Edited to explain more clearly, I hope this helps bobbym*

Hi;

I am not understanding the terminology.

A creamery has four flavors.The daily sundae has three scoops.

Four flavors of ice cream? Three scoops of what?

If you just want 3 scoops of the 4 flavors then there are

different types.

The total ways of getting a three scoop cone would be:

This is because we can get multiple stuff of one flavor.

I see you have graph paper.

You must be plotting something

Hi cooljackie;

It is not that simple, there are 64 different sundaes if the order of the scoops counts 4 x 4 x 4 = 64 but only 20 if the order does not count.

hi

Berry Kold Creamery has four flavors of ice cream: vanilla, pistachio,black walnut, and strawberry.The daily sundae has three scoops of ice cream. How many variations of the sundae are there?

To me, this means you can buy an ice cream called a daily sundae, which means you get three scoops of ice cream. You can choose the flavours for your scoops: so you could have all three different; or have some repeats. Order of repeats wouldn't matter; how you eat them is independent of the purchase order!

So I'll split the problem according to how many repeats.

(i) No repeats: I can choose 4, then 3 then 2 = 4C3 = 4

VPW; VPS; VWS; PWS

(ii) Two the same, third different: Choose the repeat in 4 ways, choose the one different 3 = 12

VVP; VVW; VVS; PPv; PPW; PPS; WWV; WWP; WWS; SSV; SSP; SSW.

(iii) All three the same. = 4

VVV; PPP; WWW; SSS

Total = 4 +12 + 4 = 20

Interestingly enough, the solution is also 6C3

If order counts? If he wants different scoops or not.

Then don't you think 64 is the answer as I said above?

No, because you count vanilla, vanilla, strawberry combination 3 times! Order does not count.

That is very good! So you agree with my answer of 20 in post #4 for when order does not count.
