# Conditional Probability and Independent Events

Course Topic(s): Probability | Basic Probability, independence | Basic Probability, conditional probability

This applet shows a discrete sample space as a rectangle with a grid of $$N_x$$ by $$N_y$$ dots. The underlying probability space is the uniform distribution on this finite set of points. Two events $$A$$ and $$B$$ are shown as smaller rectangles. The events $$A$$ and $$B$$ can be moved by dragging the interiors, and the sizes of the events (proportional to the probabilities) can be changed by dragging the corners. The probabilities $$P(A)$$, $$P(B)$$, $$(P(A)$$ intersect $$B$$), $$P(A | B)$$, and $$P(B | A)$$ are shown. The grid sizes $$N_x$$ and $$N_y$$ can be changed with text boxes.
