The contrapositive of the following statement,

“If the side of a square doubles, then its area increases four times”, is :

Consider the following two statements :

P :     If 7 is an odd number, then 7 is divisible by 2.
Q :    If 7 is a prime number, then 7 is an odd number

If  V₁ is the truth value of the contrapositive of P and V₂ is the truth value of contrapositive of Q, then the ordered pair (V₁ , V₂) equals :

The Boolean expression

$$\left( {p \wedge \sim q} \right) \vee q \vee \left( { \sim p \wedge q} \right)$$ is equivalent to :

The negation of $$ \sim s \vee \left( { \sim r \wedge s} \right)$$ is equivalent to :
