Calculate Factorial Or Permutation Of. We needed to know about factorial because it is used the formula for permutation our next topic. The factorial function symbol.
So for example if we wanted to know how many ways can first second and third place finishes occur in a race with 7 contestants there would be seven possibilities for first place then six choices for second place then five choices for third place. This symbol is for the factorial of any number you want. We can use factorials to achieve the same result.
Factorial is most commonly used to determine the permutation or combination in statistics.
We can use factorials to achieve the same result. The formula for permutations with repetition objects is as follows. Generally Factorial is one of the mathematical way used to determine or measure the product of a number with its lower value. What is Permutation Combination.
