This problem is from Example 1 in the independent events lesson. What is it? The relationship between the two is that you'll find if you do the experiment enough times, the experimental probability will get closer and closer to the theoretical probability's answer. So for example, if you're asked for the probability of getting heads after flipping a coin 10 times, the experimental probability will be the number of times you got heads after flipping a coin 10 times. It will be interesting to compare the Example: The spinner below shows 10 equally sized slices.
