Question

use the venn diagram to represent set a in roster form.
(use a comma to separate answers as needed.)
a =
venn diagram with universal set u, set a and set b. set a has numbers 2, 5 (in only a) and 9, 11 (in intersection with b). set b has 15, 16, 20 (in only b) and 9, 11 (in intersection with a). outside both sets: 23, 25

Explanation:

Step1: Identify elements in set A

Set A in the Venn diagram includes the elements only in A (the part of circle A not overlapping with B) and the elements in the intersection of A and B. From the diagram, the elements only in A are 2, 5, and the elements in the intersection (A ∩ B) are 9, 11.

Step2: List elements in roster form

Combine these elements: 2, 5, 9, 11.

Answer:

{2, 5, 9, 11}
