Question

A = {1, 3, 4, 5, 7, 9}

B = {1, 2, 4, 6, 8, 10}

List the outcomes of A∪B? What does this represent?

List the outcomes of A∩B? What does this represent?

Answer 1

A union (right side up u) B is {1,2,3,4,5,6,7,8,9,10}

A intersection(upside-down u) B is {1,4}

Explanation:

Union is taking all the numbers and joining into one set.

Intersection is taking the ones that are in both sets and joining into one set.
