If the truth value is true for the following statements :
A <---> B
A ⋁ B
G ---> ∼ D
What is the truth value of the statement B ?
I am sorry; I read the question wrong. I thought that you need to find the truth values of the first four statements.
If A \/ B is true, then A is true or B is true. In the second case, we know the truth value of B. What can you say in the first case taking into account that A <-> B is true?
