An implication or conditional "if p then q "is denoted by

If the inverse of implication p to q is defined as ~ p to ~q , then the inverse of the proposition ( p ^^ ~ q) to r is

In several fungi and plants the bisexual condition is denoted by

The conditional statement (p^^q) to p is

Write the following implications (p implies q) in the form ( ~p vv q ) and write its negation. 'If Delta ABC is isosceles then the base angles A and B are equal.'

if p,q,r are real numbers satisfying the condition p + q +r =0 , then the roots of the quadratic equation 3px^(2) + 5qx + 7r =0 are

Contrapositive of "if p· then q" is (where p and q are statement)

if P+Q=P-Q ,then

If p denotes "It is cold" and q denote "It rains" , write the statements in symbotic form. A necessary condition for it to be cold is that it rains.

Let p be "x is a fruit, " and let q be " x is ripe." Under what conditions is the statement p implies q false ?
