### Example Question #1 : How To Use A Venn Diagram

Let set , the set of all natural numbers.

= { | is a multiple of 6 }

= { | is a multiple of 9 }

Which of the following numbers would appear in the gray region of the Venn diagram?

**Possible Answers:**

**Correct answer:**

The gray area represents the portion of that is not in - in other words, all multiples of 9 that are *not* also multiples of 6.

Therefore, 4,572, 3,438, and 8,544 can be eliminated.

, so 9,349 can be eliminated because it isn't a multiple of 9.

and , so, as both a nonmultiple of 6 and a multiple of 9, 4.077 is the correct choice.

### Example Question #1 : Venn Diagrams

If two events are independent of one another, there will be no intersection of their circles on a Venn Diagram.

**Possible Answers:**

True

False

**Correct answer:**

True
