If `p : 7 gt 4, q : 7 lt 9`, then `p vv q`

If p : 5 gt 7, q : 10 lt 12 , then p vv q

If p : 7 gt 5, q : 10 lt 12 , then p ^^ q

If p, q are two propositions then (p vv ~q)^^( ~p^^q) is

Let p and q be two statements, then (p vv q)vv ~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

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

Let p and q be two statements. Then, (~p vv q) ^^ (~p ^^ ~q) is a
