Webb7 dec. 2024 · Function: since the probability density values at different (x₁, x₂) locations are generally different. Therefore, f(x₁, x₂) is a function of (x₁, x₂). Equipped with the concept of a joint PDF, we can now express the joint probability that X₁ falls in [a₁, b₁] and X₂ falls in [a₂, b₂] as a double integral:
