Probability Game  Basic concepts of Certain, Probable, Unlikely, Impossible
By: www.ixl.com
This simple online exercise introduces you to the basic principles of probability.
You will be asked a series of questions on probability, such as how likely is it that you will pick a white marble from a selection of coloured marbles shown on your screen. There will be four possible answers to choose from – certain (the right answer if all the marbles are white), probable (correct if there are more white marbles than other colours), unlikely (choose this if there are fewer white marbles than others) and impossible (if there are no white marbles at all).
This is a useful way to learn the basics of probability – an ideal activity for fourth graders.
If you get an answer wrong, a note will pop up explaining what the answer should have been – and more importantly why that was the right answer, giving you a great chance to learn as you go.
