Answer» (i) Here component statements are: p: 57 is divisible by 2. [false] q: 57 is divisible by 3. [true] Given compound statement is of the form ‘pvq’. Since, the statement ‘pvq’ has the truth value T whenever either p or q or both have the truth value T. So, it is true statement as 57 is divisible by 3. (ii) Here component statements are: p: 24 is multiple of 4. q: 24 is multiple of 6. Given compound statement is of the form ‘p ^ q’ Since, the statement ‘p A q’ has the truth value T whenever bothp and q have the truth value T. So, it is a true statement as 24 is divisible by 4 and 6. (iii) Here component statements are: p: All living things have two eyes. [false] q: All living things have two legs. [false] Given compound statement is of the form ‘p ^q’ It is a false statement. Since ‘p ^ q’ has truth value F whenever either p or q or both have the truth value F (iv) Here component statements are: p: 2 is an even number. [true] q: 2 is a prime number. [true] Given compound statement is of the form ‘p ^ q’. It is a true statement. Since ‘p ^ q’ has truth value T whenever both p and q or both have the truth value T. |
