What is combination?
In mathematics, a choice is made from a set of various elements whenever the order of a choices is unimportant (unlike permutations). For instance, there really are three possible combinations of the two fruits, an apple and a pear, if three fruits are provided, like an apple, a tangerine, and a pear. Formally speaking, a set S's k distinctive components make up a subset known as a k-combination. In other words, 2 combinations are identical only if all of their members are the same. (How the people are arranged in each set is irrelevant.) how many k-combinations there are for a set of n components
The formula below calculates how many ways there are to make an ordered list of "unique components chosen from a set of 'n' elements, in accordance with the arrangement principle:
P(N,R)= [tex]\frac{n!}{n-r!}[/tex]
p(14,5)= 14!/9!
=14*13*12*11*10
=240240
Hence, 240240 many different possible rankings are there.
