When order is not important do you use permutation or combination?
You would use combination when order does not matter.
Can a permutation be made with negative numbers?
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.
What is an arrangement in which order is important?
A permutation is the correct answer
What is a grouping of objects or events in which order does not matter?
The grouping of a subset of a set of items where the order does not matter is called a combination. One such example is the UK's National Lotto where 6 numbers have to be chosen from the 59 numbers 1-59).If there are n different items and a subset of r of them are chosen where the order of choosing does not matter then the number of combinations is given by:nCr = n!/((n-r)!r!)where n! means "n factorial" - the product of all numbers 1 × 2 × ... × n; 0! is defined to be 1.--------------------------------------------------------------------------------------------------------------------------------Where the order of selection does matter, it is called a permutation. One such example would be the order of the first three runners in a race.If there are n different items and a subset of r of them are chosen where the order of choosing does matter, then the number of permutations is given by:nPr = n!/(n-r)!
What is a permutation in mathematics?
The arrangement of objects in different orders.
