What are permutation and combination?
A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
A clerk at a bookstore is restocking a shelf of best-selling novels. He has five copies each of three different novels.
Then the number of the different ways by which he can arrange the books on the shelf will be
⇒ 15! / (5! x 5! x 5! x 3!)
⇒ 126,126
Then the number of the different ways can these books be arranged on the shelf if the copies of the same novel must be grouped together will be
⇒ 3!
⇒ 6
