Organizing outcomes - Probability

Organizing outcomes

In this section, we explain how to identify independent and random events. Two events are independent when the outcome of one event does not impact the outcome of the other event. An event is random when each outcome has an equal chance of occurring. In this section we practice determining the outcomes of two independent events and organizing these outcomes using tables and tree diagrams.
