14. Marian wants to buy a double scoop of ice cream. The ice cream shop has 23 flavours, which can be served in a regular cone,

aksik [14]

Answer:

Marian can order 1,771 combinations

Step-by-step explanation:

In this question, we are interested in calculating the number of combinations Marian can order given that there are 23 flavors that can be served in three ways.

Mathematically, the number of combinations that can be ordered is simply 23C3

This is equal to 23!/(23-3)!3! = 23!/20!3! = 1,771

The number of combinations she can order is thus 1,771 combinations
