Noun
/kjuːˈmjuːlətɪv ˈprɒbəbɪlɪti/
Cumulative probability refers to the probability that a random variable takes a value less than or equal to a certain threshold. It is often used in statistics and probability theory to express the likelihood of obtaining a result within a specific range. This concept is widely utilized in fields such as finance, economics, and various types of experiments involving statistics.
Cumulative probability is commonly used in both oral and written contexts, although technical discussions and academic writings may involve its usage more frequently.

The term "cumulative" derives from the Latin word "cumulare," which means "to heap up." The word "probability" comes from the Latin "probabilitas," which means "probability, likelihood," and is related to "probare," meaning "to test or prove." Together, "cumulative probability" reflects the idea of accumulated likelihood.
