Find AUB and ANB for the set A and B

A [4,2,9], B [7,5,1

AUB={1,2,4,5,7,9}

ANB={ }

Explanation:

AUB means that you have to combine all the element in each set whereas ANB is the set of similar elements in set A and set B. As there is no same elements in set A and set B therefore ANB will be called as null set.
