#### More specific sub-standards

Find the conditional probability of π΄ given π΅ as the fraction of π΅βs outcomes that also belong to π΄, and interpret the answer in terms of the model.

Apply the Addition Rule, π(π΄ or π΅) = π(π΄) + π(π΅) β π(π΄ and π΅), and interpret the answer in terms of the model.

Apply the general Multiplication Rule in a uniform probability model, π(π΄ and π΅) = π(π΄)π(π΅|π΄) = π(π΅)π(π΄|π΅), and interpret the answer in terms of the model.

Use permutations and combinations to compute probabilities of compound events and solve problems.
