Count Combinations of numbers N times

[Stephen_IV]

How do I use the Combin Function to count how many combinations of 5 Digit Unique Random Numbers numbers there are ranging from 0 to 9. Those 5 digits can range from 00000 to 99999?

I understand that there will be a tun of combinations i would just like a count.

Thanks in advance Stephen

Tried =Combin(1234567890,5)

Hi
you have 10 digits (1 2 3 4 5 6 7 8 9 0 ) selected 5 at a time.
So = combin(10,5) = 252 possible combinations. Waht you have tried is when you have 1234567890 (12 billion) numbers taken 5 at a time.
