Answer»

Let $A {2, 3, 5, 7} .$ Examine whether the statements given below are true or false.

(i) $\exists x \in A$ such that $x + 3 > 9.$

(ii) $\exists x \in A$ such that x is even.

(iii) $\exists x \in A$ such that $x + 2 = 6.$

(iv) $\forall x \in A, x$ is prime.

(v) $\forall x \in A, x + 2 < 10$

(vi) $\forall x \in A, x + 4 \geq 11$
