The Relationship Between a CDF and a PDF. In technical terms, a probability density function (pdf) is the derivative of a cumulative distribution function (cdf). Furthermore, the area under the curve of a pdf between negative infinity and x is equal to the value of x on the cdf. For an in-depth explanation of the relationship between a pdf and ...Apr 13, 2020 · Answer: Use the function normalcdf(-10000, x, μ, σ): normalcdf(-10000, 98, 100, 11.3) = 0.4298. Note: Since the function requires a lower_x value, we just use -10000. Example 3: Normal probability between two values.
