Fill in the truth table for the following boolean expression:
| a | b | !a || b && (a || !b) |
|---|---|---|
| T | T | |
| T | F | |
| F | T | |
| F | F |
Given the following truth table:
| a | b | expression |
|---|---|---|
| T | T | F |
| T | F | T |
| F | T | T |
| F | F | F |
Using only boolean operators (&& || !), write a boolean expression that has the truth table above.
If we lift the restriction of only using boolean operators, is there a simpler expression that has the truth table above? If so, give it.
