Bayes' 5: Bayes Theorem and Tree Diagrams There is another more intuitive way to perform Bayes' Theorem problems without using the formula. That is, using a Tree Diagram. If you look at how a tree diagram is created, these are really conditional probabilities. If we want to determine a conditional probability, the formula is 𝑃( | )= Be sure that students know that the second column of probabilities in the tree diagram are conditional probabilities. For example, the top value is P (2nd card Ace | 1st card Ace). Students will often misunderstand this value as P (1st card Ace AND 2nd card Ace), which is actually the probability in the far right of the tree diagram. Tree diagram conditional probability
