what is permutation?
Dear kara
A permutation is an arrangement of objects in a specific order. For example, if four students are scheduled to give a report in class, then each possible order in which the students give their reports is a permutation
The number of possible permutations is shown in the following table.
Number of Students Number of Outcomes1st 4 42nd 3 4 * 3 = 123rd 2 4 * 3 * 2 = 244th 1 4 * 3 * 2 * 1 = 24
We say that this is the number of permutations of 4 things taken 4 at a time,which can be symbolized as 4P4= 4 * 3 *2 * 1 = 24.There are 24 permutations;that is, there are 24 different orders in which the 4 students can give theirreports.
