i forget what the n in the factorial theorem (n/r-1) is. Does anyone know?

In statistics, "n" typically stands for the number of scores in a sample.

I hope this helps. Thanks for asking.

To clarify, the n in the factorial theorem (n/r-1) is not related to statistics or the number of scores in a sample. It seems like there might be some confusion regarding the formula you mentioned.

However, the factorial theorem itself refers to a combinatorial concept and is typically expressed as:

(n choose r) = n! / (r! * (n-r)!)

In this formula, "n" represents the total number of items or elements you have, and "r" represents the number of items you want to choose or arrange.

The exclamation mark (!) denotes the factorial function, which is the product of all positive integers less than or equal to the given number.

So, if you want to calculate the factorial of a number, you need to multiply all positive integers less than or equal to that number. For example:

5! = 5 * 4 * 3 * 2 * 1 = 120

In this case, "n" would be equal to 5.

If you have any more specific questions or need further clarification, please let me know.
