What is Combination?
Combination is a technique in maths used in selecting objects from a group of objects in a way that the order in which they are selected does not matter.
Combination formula is given as:
[tex]nC_r = \frac{n!}{r(n - r)!}[/tex]
Given the following:
- n = 12
- r = 2
Plug in the values:
[tex]12C_2 = \frac{12!}{2(12 - 2)!}\\\\12C_2 = \frac{12!}{2(10)!}\\\\12C_2 = \frac{12 \times 11}{2(1)}[/tex]
[tex]\mathbf{12C_2 = 66}[/tex]
Therefore, applying the combination formula, the number of ways there are is: 66.
