👉 Frequency math is a branch of probability theory that studies how often events occur within a dataset or over time, focusing on the relative likelihood of different outcomes. It involves calculating the frequency of events—how many times each event happens—and using these frequencies to estimate probabilities, especially in situations where exact outcomes are unknown. For example, if you roll a die many times, frequency math helps predict that each number (1 through 6) will appear roughly once every six rolls. This approach is foundational in statistics, helping to model real-world phenomena like customer behavior, disease spread, or system reliability by leveraging observed patterns to make informed predictions about future occurrences.
