A2P.DPSR.2: Use the rules of probability to compute probabilities of compound events in a uniform probability model.

Use the rules of probability to compute probabilities of compound events in a uniform probability model.

A2P.DPSR.2.1Find the conditional probability of A given B as the fraction of B's outcomes that also belong to A and interpret the answer in terms of the model.A2P.DPSR.2.2Apply the Addition Rule, P(A or B) = P(A) + P(B) - P(A and B) and interpret the answer in terms of the model.A2P.DPSR.2.3Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)*P(B|A) = P(B)*P(A|B) and interpret the answer in terms of the model.A2P.DPSR.2.4Use permutations and combinations to determine the number of possible outcomes in a sample space.
