Conditional Probability

In elementary probability, the conditional probability of an event A given an event B is the ratio P(A ∩ B)/P(B), provided P(B)>0. Visualize the events as plane regions (rectangles here) and their probabilities as the areas of those regions. Then the conditional probability P(A|B) is the fraction of B's area covered by the overlap of the two regions (purple). Use the sliders to adjust the probabilities (areas) of A and B and the black locator dots to change the location of A and B, thereby changing the overlapComponente Curricular::Ensino Médio::Matemátic
