Our math unit is about probability. During this unit, I gained more knowledge about this topic.

The new things I learned about probability are theoretical probability and experimental probability. Theoretical probability is probability expressed as ratios, fractions, percentages(number of outcomes over the number of all the outcomes). An example is heads and tails, the probability of getting heads is 50%, ½, or 1:2. Experimental probability is probability based on an experiment, it can also be written as a ratio, fraction and percentage. However, instead of the number of outcomes over all of them, it’s the number of times event occurred over the number of trials. We learned more probability language too, for instance likely, unlikely impossible, certain, probable, improbable and equally likely.

I think that that the best things I’ve learned are theoretical and experimental probability. I think this way because it’s one of the most important parts of probability. They are strategies to find the probability of something. It also taught me how to write probability in numbers(ratios, fractions, percentages). The activity that helped me the most was calculating and experimenting with theoretical and experimental probability. This helped me understand more about how to calculate the probability. In this activity, I struggled to turn a fraction like this ⅓ into a percentage. Now I have learned that you have to multiply the numerator by 100 and then divide it with the denominator.

Overall, this unit helped me learn more about probability. I thought this unit was fun and interesting because there were many fun ways to learn about this.
