Question

A= {a, b, c, d},B = {b, c, d, e}, C= {d, e, f, g}
then find (i) BUC (i) AUB iii) AU (BUC) (iv) (AUB)UC
(v) what do you notice from 3&4? ("U" refers to union)​ please answer it's urgent

Answer 1

Solution:-

GIVEN:- A = {a,b,c,d}

B = {b,c,d,e}

C = {d,e,f,g}

1.B U C = { b,c,d,e,f,g }.

2.A U B = { a,b,c,d,e }.

3.A U (BUC) = { a,b,c,d,e,f,g }.

4.(AUB) U C = { a,b,c,d,e,f,g }.

5. I observed that there are same elements.

I hope this is helpful to you
