Webb16 nov. 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.
