There are 80 different combinations of 3 cupcakes are there if order does not matter
How to determine the combination?
The given parameters are:
Flavors = 10
Flavors to choose = 3
The number of combination is calculated using:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^{10}C_3 = \frac{10!}{7!3!}[/tex]
Expand
[tex]^{10}C_3 = \frac{10 * 9 * 8 * 7!}{7!3 * 2 * 1}[/tex]
Evaluate quotient
[tex]^{10}C_3 = 80[/tex]
Hence, there are 80 different combinations of 3 cupcakes are there if order does not matter
