Question

2 circles labeled Set A and Set B overlap. Set A contains 1, set B contains 3, and the overlap of the 2 circles contains 2. The number 4 is outside of the circles.

On the Venn diagram, which region(s) represent the union of Set A and Set B (A⋃B)?

II
I and III
I, II, and III
I, II, III, and IV

Answer 1

The answer is C

Explanation:

I took the test

Answer 2

(A⋃B) = I, II, and III (C)

Explanation:

Venn diagram is used to demonstrate the relationship between two or three sets. It enables visual organisation of data in a set.

From the information:

Set A = {I}

Set B = {II}

Set A⋂B = {III}

Where ⋂ means intersection.

A⋂B = objects that belong to set A and set B

Objects not belonging to any set = 4

U = Universal set

(A⋃B) means objects that belong to set A or set B

The objects that belong to set A or set B = I, II, and III

(A⋃B) = I, II, and III (C)
