If an event, E can occur m ways out of n possible outcomes, the probability of that event is given by P(E) = (m/n). Example: 1. Problem: What is the probability of rolling a 3 on a die (plural, dice). Solution: On a fair die (not the kind you play with in Vegas, where everything is rigged), there are six equally likely outcomes when you roll. Also, there is only one way to get a 3. By the definition of proba- bility, P(3) = (1/6). Probability will always be a fraction, 0, or 1. If an event cannot happen, the probability is 0. If an event is certain to happen, the probability is 1.
