Simply defined, probability is the measure of the likeliness that an event will occur. Often represented as a number between 0 and 1, where 0 indicates impossibility and 1 represents certainty, a great deal of mystery lies within these narrow conceptual confines. This site, from Transum Mathematics, offers hundreds of probability activities, as well as links to other websites containing probability related videos, teacher resources, and more. For example, under Probability Starters, readers will find interactives such as Bus Stop, which asks the question, "How many different ways can four people stand in line." It then offers an image of four characters that can be dragged and placed around the screen to illustrate the lesson. In another lesson starter (under Advanced Probability Starters), readers will find the Best Dice activity, in which students must choose between four sets of dice to find the one that would be most likely to roll the highest numbers.
