WebAny function f (x) is potentially a P.D.F. if its satisfies two conditions: f(x) is non-negative and its integral is equal to one. Satisfying these conditions, the PDF can be greater than 1. WebFeb 16, 2024 · Similarly, to find the probability that a particular value will be greater than x1, we do 1-CDF(x1). ... In a PMF if pick a value say 1 (in the example of a dice roll) and try to find its corresponding probability of occurring then we can easily find its probability to be 0.167. However, in a PDF it is not quite that simple.
