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.
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?
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?
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
