If I create a $10$ digit password with the following requirements:
- At least one uppercase letter A-Z - $26$
- At least one lowercase letter a-z - $26$
- At least one digits 0-9 - $10$
- At least one common symbol $(\#,\$,\%,$ etc) - $32$
By inclusion-exclusion, I can calculate I have ~ $3.2333\mathtt E+19$ possible combinations
However, if I change one of the requirements to at least TWO digits 0-9, how can I calculate the possible combinations?
