Create a spinner of your choosing. Add or delete sectors, change their sizes and colors, go wild.

Make sure the Number of Spins is 1, and click the Spin button.

How does the experimental probability compare to the theoretical probability?

Click the Spin button a few more times. What happens?

Change the Number of Spins to 100, and click the Spin button.

How do the experimental and theoretical probabilities now compare?

Hit the Spin button a few more times. What happens?

What would you expect to happen if you hit the button many times?

Increase the Number of Spins to a very large number (the maximum allowed is 99,999).

Hit the Spin button one or more times?

Now compare the theoretical and experimental probabilities. What do you notice?

Was your prediction correct?

Measuring the likelihood of an event

Probability is a measure of how likely an event will occur; a flipped coin has a 50% (or 1/2) probability of landing with its head up. In these exercises, students determine the probability of events by counting the number of ways an event can happen (the numerator) divided by the total number of possible outcomes. Note that this method only works if each different outcome is equally likely to happen at any time.

In this game questions will appear in the form of "How likely is it that..." along with diagrams.

You can select your answer from four options: Certain, Probable, Unlikely and Impossible.

The first part of this game consists of some trials in which colored balls are shuffeled inside the machine.

In every trial, two colored balls are given, and you have to estimate the chance of them being picked by the machine.

The second part consists of a simulation: Balls are shuffeled inside the machine, and every time you pull the handle, a ball is picked. There is a counter for every color, and you get to see the relative frequency of the colors that were picked.

This quiz has 10 multiple-choice questions.

Click the correct answer for every question, and when you finish click the "Check Score" button.

Then you will get a full feedback where you can see your score and your correct and wrong answers, as well as a full detailed solution for every question.

This game consists of 6 different fun activities.

In these activities you can win tickets in carnival games, by making the correct calculations, and choosing the events with the highest chance of occuring.
