Answer:
6
Step-by-step explanation:
There are four different kinds of meat items in the menu.
And we are asked for the combination of 2.
So, here n = 4 and k = 2.
That is from 4 we choose 2. Hence, [tex]$ ^{n} \textrm{C}_{k} = ^{4} \textrm{C}_{2}[/tex]
We have the formula: [tex]$ ^{n} \textrm{C}_{k} = \frac{n!}{k!(n - k)!} $[/tex]
Substituting, we get:
[tex]$ ^{4} \textrm{C}_{2} = \frac{4!}{2!(4 - 2)!}[/tex]
= [tex]$ = \frac{4!}{2!. 2!} = \frac{24}{4} $[/tex]
= 6
Hence, there are six ways in which the meat combos can be made.
