Understanding Probability Concepts

Charlie Kov, a math teacher, explains that probability can be expressed as a decimal, fraction, or percentage. He uses a coin flip example to illustrate that probability is the number of desired outcomes over all possible outcomes. Probability values range between 0 and 1, where 0 means no chance and 1 means certainty.
