Let the set of all natural numbers N be the uni- versal set and K = { x :x is an even prime number} . I Find K

Set of even prime number is a

If A = {x: x is an even prime number}, then set A is empty.

Let the set I of all integers be the universal set and let A ={x: x is a negative integers be its subset . Find A'.

Find the cardinal number of the following sets. X = {x : x is an even prime number}.

Taking the set of natural numbers as the universal set, write down the complement of the set: {x:x is a prime number}
