Expert Solution
Step 1: Given:

A= {1,2,3}

B= {x,y,z}

Cartesian product:

The ordered pair in the cartesian product of sets point towards the fixed representation of the value. That is if A and B are two non-empty sets, then the cartesian product of sets A and B is the set of all ordered pairs of elements/components from A and B. In terms of mathematics formulated as:


A × B = {(a, b) : a ∈ A, b ∈ B}


Here the first element is from A and the second element is from B thus making it an ordered pair
