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.
Value | Keystrokes | Display | Description |
---|---|---|---|
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.
