**Rolling a Die Experiment**

**Question:**
You roll a die 36 times. The table shows the results. For which number is the experimental probability of rolling the number the same as the theoretical probability?

**Table:**
| Number on the Die | Frequency of Rolls |
|-------------------|-------------------|
| One               | 4                 |
| Two               | 6                 |
| Three             | 9                 |
| Four              | 5                 |
| Five              | 4                 |
| Six               | 8                 |

**Options:**
- [ ] One
- [ ] Two
- [ ] Three
- [x] Four
- [ ] Five
- [ ] Six

**Explanation:**
The theoretical probability of rolling any particular number on a fair six-sided die is \( \frac{1}{6} \). To find the experimental probability, we divide the frequency of each outcome by the total number of rolls, which is 36.

Let's calculate the experimental probabilities:
- For the number one: \( \frac{4}{36} = \frac{1}{9} \)
- For the number two: \( \frac{6}{36} = \frac{1}{6} \)
- For the number three: \( \frac{9}{36} = \frac{1}{4} \)
- For the number four: \( \frac{5}{36} \) (this does not simplify to \( \frac{1}{6} \))
- For the number five: \( \frac{4}{36} = \frac{1}{9} \)
- For the number six: \( \frac{8}{36} = \frac{2}{9} \)

From the calculations above, the experimental probability that matches the theoretical probability (which is \( \frac{1}{6} \)) is for the number two.
