Answer 1

Answer:

1) c

2) a

Step-by-step explanation:

1) Let us consider the minimum and maximum values of both sets A and B.

A has value 2n+1. Minimum value is 2*0+1=> 1 and maximum value is Infinity.

B has value 2n. Minimum value is 2*0=> 0 and maximum value is Infinity.

So, AuB belongs to Integer(Z). Therefore, answer is option c.

2) A has two elements 1 and (2,3).

P(A) = {ϕ,{1},{2,3},{1,{2,3}}}

n(P(A)) = 4. Therefore, answer is option a.
