OR Truth Table

All combinations

For OR with inputs AA and BB:


A     | B     | A || B
----- | ----- | ------
false | false | false
false | true  | true
true  | false | true
true  | true  | true

Three rows are true. Only when both inputs are false does OR return false. This makes OR more permissive than AND.
