Vocabulary • Probability is the chance that some event will occur. It is a ratio that compares the number of favorable outcomes to the number of possible outcomes. • A simple event is one outcome or a collection of outcomes. • An outcome is a possible result in a probability experiment. • Outcome occur at random if each outcome is equally likely to occur.
Vocabulary Cont. • Complementary events are two events in which either one or the other must happen, but they cannot happen at the same time. For example, a coin can either land on heads or NOT land on heads. The sum of the probability of an even and its complement is 1 or 100%.
Vocabulary Cont. • In a uniform probability model, each outcome has an equal probability of happening. • Theoretical probability is based on uniform probability- what SHOULD happen when conducting a probability experiment. • Experimental probability is based on relative frequency- what ACTUALLY occurs during such an experiment.
