Question

(A-B) UNION (A-C)
I need total explanation very soon​

Answer 1

Answer

A-B means elements of A which are not in B

A-C means elements of A which are not in C

let us understand through an example

A={1,2,3}, B={3,4,5} C={2,6,7}

A-B={1,2} (because 1 and 2 are the only elements which are not in B but are only in A)

A-C={1,3} (because 1 and 3 are the only elements which are not in C but are in A)

Now, (A-B)union (A-C)={1,2,3}

(Because union indicates the elements common in both sets )
