Correct. > If it says: > "Returns the number of combinations for a given number of objects > (repetition included)." > That would be nPr, right? The wording is a bit akward. No, "nPr" is a "permunation". nCr(a,b) = nPr(a,b) / (a-b)! Where '!' refers to "factorial". What's the name of this second function in Calc? I want to test it out. I want to figure out what they mean by "repetition included". And for reference, what's the formula for combinations? (nCr).
