How to do this quant problem on BAII Plus calculator, afternoon, remember, problem, simple

#27 on the afternoon CFAI Mock. I feel like this is a simple problem, but I can't remember how to do it on my calculator.

How do you enter this formula on the BAII Plus:

10! / (10-4)!

You have to do this:

10,
Enter,
2nd nPr,
4,

Got it, thanks for explaining (apparently my brain has turned to mush today)!

It depends if order matters or not. If the order does matter, then you would use nPr and type in 10, 2nd nPr, 6, and hit enter. If order doesn't matter, then you would do the same only using the nCr function.

Hope this helps! Hope we pass next week!
