I have 16 items and i need to know the number of possible combination for all 16 items. I know the possible number of combination for all 16 items is 1 and the possible number of combinations for 15 of the 16 items is 16 using the formula below:
[tex] \frac{n!}{r!(n-r)!}.[/tex]
How can i adaprt this formula to calculate for the number of selection from 1 to 16 inclusive without repeating the calculation 16 times.
So n will always be 16 and r will be 1 to 16 inclusive.
[tex] \frac{n!}{r!(n-r)!}.[/tex]
