Relative frequencies can help us understand probability better, but there are some challenges to keep in mind.
Dependence on Trials: Relative frequency looks at the results from a small number of tries. When you do more tries, the relative frequency can get closer to what we expect from theoretical probability. But, if you only do a few tries, like flipping a coin three times, you might get two heads. This would make it seem like the chance of getting heads is 2 out of 3, but that's not true in the long run.
Law of Large Numbers: This rule says that if you do a lot of trials, the relative frequency will be close to the theoretical probability. But doing a lot of trials can be hard because of limited time or resources.
Misinterpretation: Sometimes, students might think that relative frequencies are fixed numbers. They don’t realize that these numbers can change when more trials are done.
To help with these problems, teachers can encourage more practice with simulations and talk about variability and estimation. This way, students can gain a better understanding of probability.
