Additional Activities

Plinko is a motivating and interesting vehicle for the study of many of the important concepts that are studied in a basic introduction to probability.  There are many extensions to the activities presented in this demo that can be used as individual or group assignments or as projects.  A few of these are suggested below.

  1. Investigate the results when the size of the board is changed.  Can we generalize the patterns for finding the theoretical probabilities using Pascal's Triangle if the board is shortened or lengthened OR if we change the width?

  2. The probabilities that were presented here are conditional probabilities, i.e. we computed the probabilities that the chip would fall into a slot given that it started in a particular slot.  How would we find the probabilities that the chip would fall into a particular slot if the starting slot is randomly selected?  

  3. Suppose we drop a large number of chips from a given slot.  Can we make a prediction of the final distribution of chips at the bottom of the board?  What about the final distribution if the starting slot is randomly selected?
