Calculate Permutation with Replacement in Probability - Definition

Calculate Permutation with Replacement in Probability - Formula and Example

Definition:

An arrangement of objects into distinguishable sequences or particular order is called as Permutation.

Formula:
PR(n,r) = nrFor, n >= 0, and r >= 0.
Example:

A child has 3 pocket and 4 coins. Find the probability in how many ways can he put the coins in his pocket.

Given,

n = 3, r = 4

To Find,

Total number of ways [ PR(n,r) ]

Solution:

Substitute the value of n and r in the formula, PR(n,r) = nrFor, n >= 0, and r >= 0 Total number of ways = 34 = 3*3*3*3 = 81
