1. there should be atleast 3 capital letters 2. atleast 3 small letters -> 6 spaces gone for these, with repetitions allowed.
for 3 spaces, we have 26^3 possibilities, and they can be arranged in 10C3 ways... for the next 3, they can be arranged in 7C3 ways 3. atleast 2 numbers 0-9 now, 4 spaces left, 10 digits, 100 combinations.. 4C2 ways 4. the password should has length=10 remaining 2 spaces. assuming only caps, small and numbers, we have (26+26+10)^2 combinations.
