Conditional Probability Visualization

This animation demonstrates conditional probability by visually shrinking a sample space: it first highlights the overlap between two events within a full grid, then isolates one event to show that the probability of the other occurring is simply the ratio of their shared cells to the isolated event's total cells. It concludes by comparing the two different conditional probabilities, P(A|B) and P(B|A), to show how restricting the universe changes the outcome.
