Question

Given X = {15, 22, 33, 44, 89, 165, 1025} and Y = {-5, 15, 33, 88, 99, 150, 160, 1025}, which of the following statements is false? X Y = {-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025} X ∩ Y = {15, 33, 1025} Ø (X Y)

Answer 1

A) X u Y = {-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025}

Explanation:

Answer 2

Explanation:

Let's suppose it's a c). Ø (X Y). So X Y= X U Y ={-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025}. (X Y)=Ø is the wrong statement.
