Question:

The number of ordered triplets of the truth values of \( p, q, r \) and such that the truth value of the statement \[ (p \lor q) \land (p \lor r) \implies (q \lor r) \text{ is True, is equal to:} \]

Show Hint

Constructing truth tables is an effective way to check the validity of logical statements by analyzing all possible truth values.

Correct Answer: 7

Solution and Explanation

We are given the following logical expression: \[ (p \lor q) \land (p \lor r) \implies (q \lor r) \] We will construct the truth table to evaluate the number of ordered triplets where this statement is True.
truth table
From the truth table, we can see that the statement is true for 7 ordered triplets.
Thus, the total number of ordered triplets is 7.
