Probability density function 意味

Webb1 feb. 2024 · The area under a curve y = f(x) from x = a to x = b is the same as the integral of f(x)dx from x = a to x = b.Scipy has a quick easy way to do integrals. And just so you understand, the probability of finding a single point in that area cannot be one because the idea is that the total area under the curve is one (unless MAYBE it's a delta function).
