Procedure to find Permutations
A permutation is a number of ways in which you can select r elements out of a set containing n distinct objects in which order matters. Don't worry as you can use the formula to calculate the Permutations instantly.
P(n,r) = n!/(n-r)! for n ≥ r ≥ 0
Where P is the number of permutations in the set
n is the total number of elements in the set
r is the total number of items you choose from the set and the exclamation mark '!' is the factorial.
Remember that as per the permutations formula the number of permutations for choosing one element is simply n. However, if you have to select all the elements formula becomes P(n, n) = n!
Example: Find the number of different permutations of a box containing 5 distinct color balls taken 2 at a time?
Solution:
As per the data given n = 5
r = 2
we know the formula for permutation is nPr= n!/(n-r)!
Applying the given data in the Formula of Permutations we get the equation as such
5P2 = 5!/(5-2)!
= 5!/3!
= 20
Therefore, the number of different permutations of a box containing 5 distinct color balls taken 2 at a time is 20.
