### 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 : Data Analysis And Probability

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

**Possible Answers:**

False

True

**Correct answer:**

True

If the two events in a problem are independent, they cannot occur at the same time. That means their circle will not intersect and they will not have a shared middle section.

### Example Question #1 : How To Find Range

On the last day of school,Adam asked each of his classmates how many days of school they missed for the entire school year. He created a stem-and-leaf plot with the information.

0 | 0 0 2 4 5 6 8

1 | 0 0 1 2

2 | 3

4 | 7

What is the range of the number of days missed by Adam's classmates?

**Possible Answers:**

**Correct answer:**

To find the range of a set of data, simply subtract the smallest total from the largest total. The left side of a stem-and-leaf plot represents the ten's digit, and the right side represents the one's digit. The largest value here is 47. The smallest value is 0.
