Question

If A = {a,b,c,d) B = { b.c,e), find : (i) AUB (ii) An B (iii) B-A​

Answer 1

Answer:

(i) AUB={a,b,c,d,e}

(ii) AnB={b,c}

(iii) B-A={e}

Answer 2

Answer:

A ∪ B =  {a, b ,c, d} ∪ { b, c, e}

          =  {a, b, c , d, e}

A∩ B = {a, b, c, d} ∩ { b, c, e}

         =  {b, c}

B - A = {b, c, e} - {a, b, c, d, e}

        = {e}
