Exploring Probability using Applets

Probability is one of my favourite area for exploration. I love to do probability experiment with my students of class 10. In my earlier years of teaching I used to actually experiment using a dice , a pair of die ,rolling them 200 times , 500 times. It was time consuming. But now, with the available applets on web, it has become easier and far more interesting . One may take as many readings on just clicking a mouse. Here is list of my favourite Applets.
  • Birthday Applet - Try it... In a group of 23 (or more) randomly chosen people, there is more than 50% probability that some pair of them will have the same birthday. For 57 or more people, the probability is more than 99%, tending toward 100%.
  • Tossing a coin Applet - Toss a coin as many times and calculate the probability of getting a Head or a Tail.
  • Spinner Applet - An interesting one to experiment on probability of spinning.
  • Racing Game with two dice
  • Marbles Applet

I still think there is value in having the students actually roll the dice to get a feeling for why the probabilities work the way they do. Then move to the applets (for the case of large trials).

Thanks 4 ur comment.
Yes , I do agree to it. In our classroom we do small experiments by actually rolling a dice , throwing a coin etc and then we switch over to using these kinds of applets.
