Question

IF A{1,2,3,4,5},B={3,4,7,8} THEN FIND A UNION B AND A INTETSECTION B

Answer 1

Hey there

Here ur answer

Before moving to ur ans

Let me tell u simple definition for both union and intersection.

Union:

we should join all the sets and write. repeated should be avoided.

Intersection:

we should write only common terms.

Given:

A={1,2,3,4,5}

B={3,4,7,8}

Sol:

A UNION B                = {1,2,3,4,5} union {3,4,7,8}  

                                   = {1,2,3,4,5,7,8}  

A INTETSECTION B  ={1,2,3,4,5} intersection {3,4,7,8}

                                   ={3,4}

So,∴ A UNION B   = {1,2,3,4,5,7,8}  and  A INTETSECTION B  = {3,4}

Hope this helps u
