Question No. 14Marks : 1.00    B is true           Neither A nor B is true           Either A or B can be true depending upon situation           A is true

Question No. 15Marks : 1.00    Mutually inclusive           If two literals are not negation of other           If two literals are negation of other           Mutually exclusive

The truth value of the proposition "p OR q" is true if:a.Both p and q are trueb.Either p or q is truec.Neither p nor q is trued.Both p and q are false

Directions: In the following questions, the symbols ⋆, &, @, ©, and # are used with the following meaning as illustrated below: ‘A @ B’ means ‘A is neither greater than nor equal to B’. ‘A # B’ means ‘A is neither smaller than nor greater than B’. ‘A * B’ means ‘A is not greater than B’. ‘A & B’ means ‘A is greater than B’. ‘A © B’ means ‘A is either greater than or equal to B’. Now, In the following question assuming the given statements to be true, find which of the conclusions I, II & III given below them is/are definitely true? Statements: M & P, P © Q, Q * R, R @ S Conclusions: I. S # M II. P © R III. Q @ S Options Both Conclusions I and II are true. Both Conclusions I and III are true. Only Conclusion III is true. Either Conclusion I or III is true. Neither Conclusion I nor III is true.

The compound proposition "p AND q" is true only when:a.Either p or q is trueb.Both p and q are truec.Neither p nor q is trued.None of the above

what is the contradiction (in proof by contradiction) in the statement "If A, then B"?
