Permutations and combinations are used to select arrange a certain number of quantities from a group of quantities in a certain order. When we choose quantities at random, we use combinations to select them.
But when we have to select and arrange them in a particular order, we use permutations to do the same. For example if we have to select 2 balls out of the total 10 balls, then we can choose any 2 balls using combinations but if we have to arrange those 2 balls at a particular place, permutations will be used.
A deck of cards contain 52 cards.
Ways to select 5 cards at random from a deck of 52 cards will be given using combinations as those 5 cards are not to be arranged in a particular order. The cards would be received at random.
Which means that there are 2598960 ways to distribute 5 cards.
