### Example Question #11 : Basic Statistics

You are given the following data:

What is the range?

**Possible Answers:**

**Correct answer:**

Recall that we find the range of a set of data by subtracting the smallest value from the largest value. In this case, the smallest value is and the largest value is . Thus, our range is .

### Example Question #1 : Understanding Range

There are girls and boys running a race. What is the probability that only boys will finish in the top three places?

**Possible Answers:**

**Correct answer:**

Probability is a fraction between and . The numerator is the total number of ways to get what you want, or a subset of the sample space. The denominator is the total ways, or complete sample space.

The number of ways only boys would finsih in the top three places:

The number of ways all contestants can finish the race:

So the probability of only boys finishing in the top three places is given by the fraction when simplified.
