QUESTION: If your target object is shaped like the one on the applet, what is the probability that your dart will a) land anywhere inside the rectangle?, b) land anywhere inside the square but outside the rectangle?
Simulate by clicking on the 'Place Point' button to randomly place a dart somewhere in the square - you can use this to see how well your experimental probability matches with your theoretical probability. Click the 'Reset' button to reset the experiment.
Without using simulation, how will you calculate the answer to the question above?
You can drag the vertices of the blue shape to make it as big or as small as you like. Overlap two of the vertices to fool it into thinking it's a triangle.
