Description:

Addition Rule of ProbabilityThere are many rules associated with solving probability problems. This lesson deals with the addition rule. The addition rule helps you solve probability problems that involve two events. Even though we discuss two events (usually labeled A and B), we’re really talking about performing one task (rolling dice, drawing cards, spinning a spinner, etc.) and finding about the probability of two things happening in that one task.An excellent tutorial with interactive exercises from algebralab.org
