WebLet X be a random variable. Then the function F(x) is defined by F(x)=P(X=x) is called a probability distribution function of a random variable X. WebNov 16, 2024 · Probability density functions can be used to determine the probability that a continuous random variable lies between two values, say a a and b b. This probability is denoted by P (a ≤ X ≤ b) P ( a ≤ X ≤ b) and is given by, P (a ≤ X ≤ b) = ∫ b a f (x) dx P ( a ≤ X ≤ b) = ∫ a b f ( x) d x Let’s take a look at an example of this. In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be equal to that sample.
