If I had to pick a 4 number combination eg/ 2657 using the numbers 0 thru 9, how many different combinations would there be?

Is there a formula to use? Software ? I would like to know.

Thanks

With your specific case, just normal counting will reach every possible combination. 0000 to 9999 for a total of 10,000 different possible combinations.

If I remember correctly, the formula is

x[sup]y[/sup]

Where x is the number of digits, and y is the number of locations.

In your case, there are 10 possible digits (0 - 9) and 4 possible locations. 10[sup]4[/sup] = 10,000
