What is the formula for probability and statistics combination?
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.

The formula for permutation is nPr = n! /(n-r)! | The formula for combination is nCr = n!/[r!(n-r)!] |
What is the formula for combinatorics and probability?
The four combination probability equations are:
Permutation with repetition: Total permutations = n^r.
