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 digit from $0-9$ : $10$
- 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?
