Conditional Probability and Bayes
by Anonymous
Add a condition and watch the denominator shrink out of 100, then trace the probability tree backward to see whether a positive test really means disease.

About this app
An interactive high-school probability lesson on conditional probability and Bayes' theorem. Explore how conditioning changes the denominator, calculate branch probabilities by multiplying along a probability tree, and work backward from a positive medical test to estimate the chance of true illness.
