Thus you are looking at all possible combinations of values of X and Y that add to z. This is why you needed to "add each item from X to each item from Y" when verifying that E(X + Y) = E(X) + E(Y). E(X) is the expectation value of the continuous random variable X. x is the value of the continuous random variable X. P(x) is the probability mass function of X. Properties of expectation Linearity.

where k is any nonzero constant, appears so often in the following set of problems, we will find a formula for it now using u-substitution so that we don't have to do this simple process each time. Begin by letting. u = kx. so that. du = k dx , or. (1/ k) du = dx .

ey = x e y = x Take the natural logarithm of both sides of the equation to remove the variable from the exponent. ln(ey) = ln(x) ln (e y) = ln (x) Expand the left side.

E [ X + Y] = ∫ − ∞ ∞ ∫ − ∞ ∞ (x+y)f (x,y)dxdy. = ∫ − ∞ ∞ ∫ − ∞ ∞ x f ( x, y) d y d x + ∫ − ∞ ∞ ∫ − ∞ ∞ y f ( x, y) d x d y. Take log of both sides ylogx= x-y Rearrange the equation ylogx +y=x y(logx+1)=x y=x/(logx+1) Differentiate it w.r.t. x dy/dx={(logx+1)-x/x}/(logx+1)^2 = (logx+1–1 y=e^x. Loading y=e^x. y=e^x.

ln'ing that is like square rooting the square. (sqroot)y=x is what that would be rearanged in terms of x.

In particular E(X2jY) is obtained when g(X)=X2 and Var(XjY)=E(X2jY)¡[E(XjY)]2: Remark. Note that E(XjY) is a random variable whereas E(XjY =y) is a number (y is ﬁxed). Theorem 1. (i) E[E(XjY)]= E(X). (ii) Var(X)=Var[E(XjY)]+E[Var(XjY)].

By definition E (X ∣ Y) is random variable which satisfies: E (X ⋅ 1 G) = E (E (X ∣ Y) ⋅ 1 G), for all G ∈ σ (Y). Simply take G = Ω such that 1 G = 1 and you get the desired result.

When a is constant and X,Y are random variables: E(aX) = aE(X) E(X+Y) = E(X) + E(Y) Constant. When c is constant: E(c) = c.
