Q.Construct the truth table for the following statement pattern: $(p \land q) \leftrightarrow (q \lor r)$

Letters standing for unspecified statements (p, q, r, ...) are called statement letters, and any well-formed combination of statement letters with connectives (∧, ∨, →, ↔, ~) is called a statement pattern or proposition; the individual statement letters appearing in it are its prime components. A truth table for a statement pattern with n distinct prime components systematically lists all 2ⁿ possible combinations of T/F for those components (2 components → 4 rows, 3 components → 8 rows) and works out, column by column, the truth value of every intermediate sub-expression until the final column gives the truth value of the whole pattern for each combination. When a pattern mixes several connectives without brackets, they are evaluated in the fixed priority order ~, ∨, ∧, →, ↔ (negation first, biconditional last), exactly the way multiplication is evaluated before addition in ordinary algebra.
