Is this a well formed formula ( WFF )

( P v Q ) ( R S)

Please Use truth table definitions to answer the following questions.

1. If ( R S) is false, and R is False, then what is S?

2. If R v S is true, and S is true, then what is R?

Given the formula (P V Q)) - (R A .5), let's proceed with answering the questions using truth tables. If l(R A |S) is false, and R is False, then S must be True. Here's the truth table for l(R N -S| RA~AS (f\\ 15) F F T F R\\|S T From the truth table, we can see that when R is False and .S is True, (R N 15) is True. Therefore, the given condition holds. If R \\/ Sistrue,and S is true, then IR could be either True or False. Since the disjunction R \\V .S is True as long as one of its operands is True, and in this case, S is True, R could be either True or False for the disjunction to be true. Therefore, we cannot determine the exact value of I given the information provided
