Calculates the number of permutations of r objects that can be chosen from a set of n objects, nPr.
n: The number of objects to choose from.
r: The number of objects to chosen from set n.
Compute the permutation of 2 cards possible from a deck with 47 cards.
|47||n||47.00||Stores the n value.|
|2||r||2.00||Stores the r value|
|npr||2,162.00||Calculates the number of permutations.|
Due to the nature of this function, it is difficult to solve for the n or r values.
