To find the experimental probability of rolling a total of 9 on two number cubes, we need to determine the number of times the total of 9 was rolled and divide it by the total number of trials.
From the given results, we can see the following pairs that have a total of 9:
(3, 6)
(4, 5)
(4, 5)
(6, 4)
(2, 1)
(1, 6)
There are 6 trials where the total is 9. Since there were 50 total trials, the experimental probability of rolling a total of 9 is:
Experimental probability = Number of favorable outcomes / Total number of outcomes
Experimental probability = 6 / 50
Experimental probability = 0.12 or 12%
Therefore, the experimental probability of rolling a total of 9 on two number cubes, based on the given 50 trials, is 12%
1. The students rolled two number cubes 50 times and wrote down the results.
2. They counted the number of times the dice added up to 9.
3. They found that the dice added up to 9 six times.
4. To calculate the experimental probability, they divided the number of times the dice added up to 9 (6) by the total number of trials (50).
5. They simplified the fraction and found that the experimental probability of rolling a total of 9 was 6/50 or 0.12.
6. The experimental probability is the likelihood of an event happening based on the results of an experiment.
7. In this case, the students found that there is a 12% chance of rolling a total of 9 on two number cubes based on their 50 trials.
8. The formula used to calculate experimental probability is:
Experimental probability = Number of favorable outcomes / Total number of outcomes
9. The name of the formula is "Experimental Probability."
10. It is important to watch the number of trials and make sure there are enough trials to get accurate results.
11. For example, if the students rolled the dice only 10 times, the experimental probability might not be as reliable.
12. A real-world example of experimental probability could be flipping a coin to see how often it lands on heads. By flipping it many times, we can calculate the experimental probability of getting heads.

Here is the answer rewritten in easy-to-understand terms:
There are 4 ways to roll a 9 on two number cubes. In the simulation, there were 2 instances of rolling a 9, so the experimental probability of rolling a 9 is 2/50 = 0.04.
Here is the answer rewritten in a numbered list format:
1. There are 4 ways to roll a 9 on two number cubes.
2. In the simulation, there were 2 instances of rolling a 9.
3. The experimental probability of rolling a 9 is 2/50 = 0.04.
Here is the answer rewritten in a brief format:
The experimental probability of rolling a 9 on two number cubes is 2/50 = 0.04. This means that out of 50 trials, there were 2 instances of rolling a 9.
Here is the answer rewritten in a synopsis format:
In a simulation of 50 trials, there were 2 instances of rolling a 9 on two number cubes. This gives an experimental probability of 2/50 = 0.04.
Here is the answer rewritten in an abstract format:
The experimental probability of rolling a 9 on two number cubes is 2/50 = 0.04. This means that out of 50 trials, there were 2 instances of rolling a 9.
Here is the answer rewritten in a simple and easy 1st grade analogy:
If you flip a coin 50 times, you would expect to get heads about 25 times. This is because there are two sides to a coin, and each side has an equal chance of landing face up. Similarly, if you roll two number cubes 50 times, you would expect to get a total of 9 about 2 times. This is because there are 4 ways to roll a 9, and each way has an equal chance of occurring.
Here is the answer summarized in 1 sentence:
The experimental probability of rolling a 9 on two number cubes is 2/50 = 0.04.
Here is the answer to the math part:
```
Total number of trials: 50
Number of trials where a 9 was rolled: 2
Experimental probability of rolling a 9: 2/50 = 0.04
```
Here is the formula used:
```
Experimental probability = (Number of successes / Total number of trials)
```
Here is the name of the formula:
The formula used is called the experimental probability formula.
Here is what to watch:
When calculating the experimental probability, it is important to make sure that the total number of trials is large enough to be representative of the actual probability. If the total number of trials is too small, the experimental probability may not be accurate.
Here is an example:
If you roll two number cubes 10 times, you might not get a total of 9 at all. This does not mean that the experimental probability of rolling a 9 is 0. In fact, the experimental probability of rolling a 9 is still 2/50 = 0.04. However, because the total number of trials is so small, the experimental probability may not be accurate.
