Combination formula :

1. Combination is defined as a selection of r things that can be done out of total n things. This is denoted by nCr, which is equal to n!/r!(n-r)!

2. As per the Fundamental Principle of Counting, if a particular thing can be done in m ways and another thing can be done in n ways, then either one of the two can be done in m + n ways and both of them can be done in m × n ways.
