Combinations and Permutations


Permutation and combination related questions are common in PSC and Bank exams.

Before going to Combinations and Permutations, first lean about factorial. .

If \'n\' is a positive integer then, factorial of n is denoted as n! . .

5! = ( 1 x 2 x 3 x 4 x 5 ) = 120.

4! = (1 x 2 x 3 x 4 ) = 24.

Permutations are for lists of items, whose order matters and combinations are for group of items where order doesn’t matter. in other words, .

When the order of items doesn\'t matter, it is called as Combination.
When the order of items does matter it is called as Permutation.

The number of permutations of n objects taken r at a time is determined by using this formula:.

P(n,r)=n!/(n−r)! .
