How did you decide how to make each spinner? P green is close to 1 3 , which is 33.
In cases where the theoretical probability cannot be calculated, we need to rely on experimental probability. They may also notice that the numbers are closer to each other than results for their 30 rolls. Students should see that the numbers are pretty close to each other because the probability of each number is the same.
Performance Task Ways of Thinking: New math lessons Email. It should be noted that in order for experimental probability to be meaningful in research, the sample size must be sufficiently large. Goals and Learning Objectives Learn about experimental probability. They will compare experimental results to expected results by first conducting an experiment, then calculating the probability of an event.
Possible answer: The spinner should have equals areas of red and blue and a very small area for yellow. Search over 500 articles on psychology, science, and experiments.Comparing theoretical to experimental probabilites - 7th grade - Khan Academy
The theoretical probability is defined as the ratio of favorable outcomes to the total number of possible outcomes, often simply called probability.
