Final answer:

To construct the truth table for (p∧q)∨r, evaluate the statement for all possible combinations of truth values for p, q, and r. There are 2⁹ combinations. Here is an example table with the final truth values of the statement.

Step-by-step explanation:

A truth table is used to determine the possible truth values of a compound statement. To construct the truth table for the statement (p∧q)∨r, we consider all possible combinations of truth values for p, q, and r and evaluate the statement for each combination. Here is the step-by-step process:

  1. Start by listing all possible combinations of truth values for p, q, and r. There are 2 possible truth values for each variable, so there are a total of 2⁹ combinations.
  2. Evaluate the statement (p∧q)∨r for each combination of truth values.
  3. Write the truth values of the statement in the final column of the truth table.

For example:

pqr(p∧q)∨rTTTTTTFTTFTTTFFTFTTTFTFFFFTTFFFF

Final Answer:

The truth table for the statement (p∧q)∨r is as follows:

| p | q | r | (p∧q)∨r |

|---|---|---|---------|

| T | T | T | T |

| T | T | F | T |

| T | F | T | T |

| T | F | F | F |

| F | T | T | T |

| F | T | F | F |

| F | F | T | T |

| F | F | F | F |

Explanation:

The truth table for the statement (p∧q)∨r evaluates the possible truth values of the statement based on all combinations of truth values for the variables p, q, and r. The logical operation used here is the disjunction (∨), which is the "OR" operation. Firstly, the conjunction (∧) operation is performed between p and q, and then the result is combined with r using the disjunction operator.

In the truth table, each row represents a unique combination of truth values for the variables p, q, and r. The (p∧q) part evaluates the conjunction of p and q, and then the ∨r operation combines this result with r using the "OR" logic. The final column (p∧q)∨r shows the resulting truth values for the entire statement based on these combinations.

The statement (p∧q)∨r will be true (T) if either the conjunction of p and q is true (irrespective of r) or if r itself is true, or if both conditions are true. Otherwise, the statement evaluates to false (F).
