See Example. When the outcomes of an experiment are all equally likely, we can find the probability of an event by dividing the number of outcomes in the event by the total number of outcomes in the sample space for the experiment.

It defines odds in favor and against, illustrating how to express them as ratios. The formula for calculating the probability from given odds is provided, along with examples and exercises to enhance understanding. The importance of differentiating between odds and probabilities in communication is underscored throughout.

It highlights the negative expected value often faced by players in gambling scenarios. Additionally, it covers expected values in life insurance and raffles, emphasizing their financial implications. Historical figures Blaise Pascal and Pierre de Fermat are referenced for their contributions.
