If there are n objects and you have to choose r objects then the number of permutations is (n!)/((n-r)!). For circular permutations if you have n objects then the number of circular permutations is (n-1)!

Yes, a permutation can be made with negative numbers. In mathematics, a permutation is an arrangement of objects in a specific order. Negative numbers can be included in a permutation just like any other integer. The order in which the negative numbers are arranged would be considered a valid permutation.
Yes
Permutation Formula A formula for the number of possible permutations of k objects from a set of n. This is usually written nPk . Formula:Example:How many ways can 4 students from a group of 15 be lined up for a photograph? Answer: There are 15P4 possible permutations of 4 students from a group of 15. different lineups
A permutation is the correct answer
The arrangement of objects in different orders.
