WebSep 8, 2024 · 1 Yes, your calculations are correct and you even stated the reason why the expectation of Y is in terms of x: it is because of the limits of integration. Perhaps it might help to recall the notation from calculus F(x) = ∫x af(t)dt. Notice, F is a function of x, as t is … The marginal probability is the probability of a single event occurring, independent of other events. A conditional probability, on the other hand, is the probability that an event occurs given that another specific event has already occurred. This means that the calculation for one variable is dependent on another variable. The conditional distribution of a variable given another variable is the joint distribution of both va…
Web1 Answer Sorted by: 1 We interpret the picture as follows: the joint distribution is uniform on the shaded region. Then the joint density is 4 on the shaded region, and 0 elsewhere. For the expectation of X, there is no reason to compute. Symmetry shows that E ( X) = 0.5. For the expectation of Y, we could also use geometry, but let us integrate. http://cs229.stanford.edu/section/more_on_gaussians.pdf

If we consider E[XjY = y], it is a number that depends on y. So it is a function of y. In this section we will study a new object E[XjY] that is a random variable. We start with an example.
