3332, 3323, 3233 and 2333 are made of the same numbers but are different and you have to count all four, that's why we are going to use variations - the order matters!
You can also see that repetitions are included. If you look it up, the formula needed in such case is nr where n is the number of elements (10) and r is the order of the sequence (4)
V = 104 = 10 000
But if you are looking for combinations the order doesn't matter, though you still have to include repetition
You use the binomial symbol Binomial[n+r-1,r] = (n+r-1)!/(r!*(n-1)!)
C = 13!/(4!*9!) = 13*12*11*10*9!/(4*3*2*9!) = 13*11*5 =715
Still a lot, though :D
