Is the selection a permutation, a combination, or neither?
Sam rents 5 videos from a video store.
Solution:-
Use the definition of permutation and combination to determine the type of selection made.
A permutation of a set of n distinct object is an arrangement of the objects in a specific order without repetition.
A combination of a set of n distinct objects is an arrangement of the object without repetition where order is irrelevant.
In the selection process of the problem, the order that the video are rented is not important.
There will not be ant renting video form the video store because the student cannot rent the same copy of a movie multiple time at the same moment in time.
Use the fact that the selection process has no repetition and order is irrelevant to determine the type of selection.
The selection is a combination.
