Homer Simpson is standing on the edge of a cliff.
A coin is thrown to decide which way he will move.
On heads, he will move left, on tails right.

Homer Simpson falling from a cliff
The above link shows Homer Simpson standing on the edge of a cliff. This time there
is a 1/3 chance he steps forward, and a 2/3 chance he steps away from the cliff. Run
the applet 20 times and calculate the probability he falls and the probability he is
saved.
Multiple
Trials
This applet will run the above simulation 100, 10000 and 1000000
times. What is the probability Homer is saved for each of these?
What do you think the theoretical probability may be for this
scenario?
In this game Homer either moves up (heads) or left (tails) on each throw of the coin. If he reaches the top left box
he wins. If he goes outside of the blue square he loses.
