Here's another hint. If it was one letter and one number in the password and you had to find how many combinations was possible, you would count them by saying: for each of the 26 letters, there are 10 numbers. I.e. for A there is 0,1,2...,10. Same for B, C,...
So, total number of combinations is 26*10 = 260.
Now, apply the thinking to your own problem.
