WebBroadly speaking, joint probability is the probability of two things* happening together: e.g., the probability that I wash my car, and it rains. Conditional probability is the probability of one thing happening, given that the other thing happens: e.g., the probability that, given that I wash my car, it rains. WebThe joint density function of two continuos random variables X and Y is given by: f ( x, y) = 8 x y if 0 ≤ y ≤ x ≤ 1 and 0 otherwise. Calculate P ( X ≤ 1 2) Calculate P ( Y ≤ 1 4 ∣ X = 1 2) Calculate the expected value of Y 3 if X = 1 2. I would just like to check whether I am solving these questions in the right way. WebApr 12, 2024 · Therefore, both marginal and conditional distributions depend on the joint probability distribution of the variables being observed. Third, both marginal and conditional distributions sum to 1. Summing over all possible values of the variable gives the combined probability distribution, which must be equal to 1. sold delray beach
