Question

A=(1,2,3,4) and B=(2,4,6,8) findA union B and A
intersectionB

Answer 1

Answer:

A ∪ B = {1,2,3,4,6,8}

A ∩ B = {2,4}

Step-by-step explanation:

1.    A ∪ B

Union of two sets is set of those elements which are present in both but common elements are included just once.

So, here 2 and 4 element are common in both sets so in their union both are included just once and other elements which are uncommon should also be included in their union set.........

∴ A ∪ B = {1,2,3,4,6,8}

2.   A ∩ B

Intersection of two sets are simply the set which contains those elements which are common in both the sets.

So, here common elements are 2 and 4......

∴ A ∩ B = {2,4}
