Having a bit of trouble understanding the truth table for the statement:
Could somebody run me through the scenarios and explain how they affect the truth value of . In particular, the scenario where is false, but is true... how does this imply that is true?
true, true: ?
true, false: ?
false, true: ?
false, false: ?
I know the answers are true, false, true, true. But can someone explain the logic behind it?
