Probability quantifies how likely an event is to occur, calculated by favorable outcomes ÷ total possible outcomes. For instance, flipping a fair coin yields two possible outcomes: heads or tails. The probability of heads is 1/2. When rolling a six-sided die, the probability of rolling a 4 is 1/6. Basic probability helps you analyze games of chance, forecast risk in business, or interpret scientific experiments. Mastery of this fundamental approach sets the stage for more complex topics like compound events, conditional probability, and statistical inference.
