Question

If A={5,7,9,11,13,15} and B ={7,8,11,15,20} and C = {5,8,9,11,13,15,17,20}.What is the value of A n ( B n C).

Answer 1

Hope this helps you ;)

A = {5, 7, 9, 11, 13, 15}

B = {7, 8, 11, 15, 20}

C = {6, 8, 9, 11, 13, 15, 17, 20}

A n ( B n C )

= {5,7,9,11,13,15} n [ {7,8,11,15,20} n {5,8,9,11,13,15,17,20} ]

= {5,7,9,11,13,15} n {8, 11, 15, 20}

= {11, 15}

Answer 2

Answer:

If A={3,5,7} and B={5,7,9 ) and C={7,9,11 ) Verify (AnB)x(BC).
