factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7. Factorial zero is defined as equal to 1.
How do you explain factorial?
Factorials are very simple things. They’re just products, indicated by an exclamation mark. For instance, “four factorial” is written as “4!” and means 1×2×3×4 = 24. In general, n!
What is factorial in statistics?

What is a factorial and how does it work?
A factorial is a function in mathematics with the symbol (!) that multiplies a number (n) by every number that precedes it. In more mathematical terms, the factorial of a number (n!) is equal to n(n-1). For example, if you want to calculate the factorial for four, you would write: 4!

What is the factorial of 0 with no factors?
The factorial of 0 is 1 i.e., 0 ! = 1 According to the convention of empty product, the result of multiplying no factors is a nullary product. It means that the convention is equal to the multiplicative identity.
