Question

write the truth value of the 4 is odd or 1 is prime​

Answer 1

Let p : 4 is odd.

Let q : 1 is prime.

Then the symbolic form of the given statement is p∨q.

The truth values of both p and q are F.

∴ The truth value of p∨q is F ...... [F∨F≡F]

Answer 2

The truth value of the 4 is odd or 1 is prime​ is F.

• The truthfulness or falsity of a proposition is called its truth value.
• If a proportion is true, then its truth value is denoted by 'T' and if it is false, then its truth value is denoted by 'F'.

• Let p be the proposition '4 is odd' and q be the proposition '1 is prime​'.
• The compound proposition 'p or q' is known as disjunction. It is denoted by p ∨ q.
• The disjunction of the two propositions p and q is false if the disjuncts are both false otherwise it is true.
• 4 is not an odd number, it is an even number.
• 1 is not a prime number.
• Since both the propositions are wrong, the truth value is F.
