" The dual of "(p rarr q)vv(q-p)" is "

The negation of p rarr (~ p vv q) is

The statement (p rarr q)vv(q rarr p) is

Observe the following statements I : The dual of [ ~p ^^ q)] vv [ p ^^ {~(q vv ~s)}] is [~(p vv q)] ^^ [p vv{~(q ^^ ~s)}] II : The dual of ~p ^^ [(~q) ^^ (p vv q) ^^ ~r] is ~p vv[~q) vv(p ^^ q) vv ~r] The true statements in the above is/are :

Observe the following statements I : The dual of [ ~p ^^ q)] vv [ p ^^ {~(q vv ~s)}] is [~(p vv q)] ^^ [p vv{~(q ^^ ~s)}] II : The dual of ~p ^^ [(~q) ^^ (p vv q) ^^ ~r] is ~p vv[~q) vv(p ^^ q) vv ~r] The true statements in the above is/are :

The truth table of (~p) vv q rArr p is

If p is true and q is false then the truth values of (p harr q) harr (~q to ~p) and (~p vv q)^^(~q vv p) are respectively
