Fundamental Principle of Counting Subtitle: Data Science and A.I. Lecture Series Fundamental Principle of Counting Statement: If one event can occur in m ways and another event can occur in n ways, then the two events together can occur in m × n ways. This principle can be extended to multiple events. For example:Total ways […]
