Where n is the number of choices (21 consonants) and r is the group size (13). Order doesn't matter and repetition isn't allowed

The answer here is 203490.

nCr where n=21 and r=13

The formula is n!/(r!*(n-r)!)

So 21!/(13!*8!)

I think, LOL!

About tree fiddy.

Reminds me of a line I read at 14 in the Penthouse magazine (it must have been a typo)

Oh, so post number 4 didn't get this blessing... I see how it is!I'm so slow! The answers in posts #2 and #3 are correct. @Davism72 and I even use the same calculator!

I thought it goes without saying . . .Oh, so post number 4 didn't get this blessing... I see how it is!

You forgot to multiply out when completing the formula.Oh, so post number 4 didn't get this blessing... I see how it is!

F(x) = tree fiddy * z

where z = 581.4

You want all 203,490 combinations?Now then, anyone here an excel guru? I got a hell of puzzle I'm trying to sort through.

Not really, but gonna need to narrow it down a bit using Excel and a couple of parameters.You want all 203,490 combinations?

Learning something in middle school is one thing. Remembering it in your 40's is another.

I guess it makes you a memory savant.Learning something in middle school is one thing. Remembering it in your 40's is another.

edit: missed above comments no need to call in folks for answers

Shoot me a PM what you are looking forNot really, but gonna need to narrow it down a bit using Excel and a couple of parameters.

You should see if you can find someone with access to Tableau. They can create parameters that you can adjust and recalculate the results on the fly. Makes what if's much easier. I would be more than happy to do it for you, but that would result in misappropriation of govt resourcesNot really, but gonna need to narrow it down a bit using Excel and a couple of parameters.

Sending you a PM now.Shoot me a PM what you are looking for

There's also a COMBINA, that includes "repetitions", or counts items a different order as an additional result, I think. So COMBINA result should always be higher than COMBIN.
