WebNov 27, 2024 · Why is area under density 1? The area under a density curve represents probability. The area under a density curve = 1. These two rules go hand in hand because probability has a range of 0 (impossible) to 1 (certain). Hence, the total area under a density curve, which represents probability, must equal 1. WebThe area under the density curve between two points corresponds to the probability that the variable falls between those two values. In other words, the area under the density curve between points a and b is equal to \(P(a < x < b)\).
