I have a math related problem:

On my calculator I have the nCr function, which can calculate combinations. Is there a same function for it in vb??

An example:
I want to fill 3 squares in a 4 x 4 rectangle. On how many ways can I do this. Some possibillities are:

x - x -
- - - -
- - - -
- x - -

or

- x - x
x - - -
- - - -
- - - -

To count the number of combinations you can use the nCr functions:
Answer = (4 x 4) nCr 3 = 16 nCr 3 = 560 possibillities.

Note:
16 nCr 3 = 16! / (3! * 13!) =
(16 x 15 x 14 x 13 ... x 3 x 2 x 1) / ((3 x 2 x 1) x (13 x 12 x 11 ... x 3 x 2 x 1))

Anyone knows if this function exists in vb??

These function do not exist, but it shouldn't be to hard to write them yourself.

No, but I was just curious if it existed. Then I'll just write it myself. Thanks anyway
