Statement 1: If `p ,q ,

Statement-1 : ( p ^^ ~ q) ^^ (~ p ^^ q) is a facllocy. Statement -2: ( p to q) harr ( ~ q to ~ p) is a tautology .

A man P speaks truth with probability p and another man A speaks truth with probability 2p. Statement-1 If P and Q contradict each other with probability (1)/(2) , then there are two values of p. Statement-2 a quadratic equation with real coefficients has two real roots.

Statement-1 : ~ (p hArr ~ q) is equivalent to p hArrq. Statement-2: ~ (p hArr q) is a tautology

Let p statement If 2>5 then earth will rotate and q be the statement 2>15 will not rotate.Statement-1:p and q are equivalent.Statement- -2:m rarr n and sim m vv n are equivalent.

Construst truth tables for the following statements : ~(p ^^-q) " "(ii) ~[(~p) vee(~q)] " "(iii) (p ^^q) ^^ (~p)

The statement p vv q is

Prepare truth tables for the following statements : (1) (p^^q)to(~P) (2) ~(~p^^~q)vvq (3) pto[~(q^^r)]

Consider two statements S_1:~p to (~q implies~p) is a tautology S_2:(~q^^p) to q is a fallacy then
