Web1 Answer. Suppose X is a discrete random variable with pmf p ( x). Then, by definition, E ( a X + b) = ∑ x ( a x + b) p ( x) = ∑ x ( a x ⋅ p ( x) + b ⋅ p ( x)) = ∑ x a x ⋅ p ( x) + ∑ x b ⋅ p ( … WebIn Section 5.1.3, we briefly discussed conditional expectation.Here, we will discuss the properties of conditional expectation in more detail as they are quite useful in practice. We will also discuss conditional variance.

Weband b = 1 a = 1 0:42 )b = 0:58. Therefore if the investor invests 42% of the available funds into IBM and the remaining 58% into TEXACO the variance of the portfolio will be minimum and equal to: V ar(0:42X + 0:58Y ) = 0:422(0:0061) + 0:582(0:0046) + 2(0:42)(0:58)(0:00062) = 0:002926: The corresponding expected return of this porfolio … Web8 aug. 2024 · Using this as a guide, we define the conditional statement P → Q to be false only when P is true and Q is false, that is, only when the hypothesis is true and the conclusion is false. In all other cases, P → Q is true. This is summarized in Table 1.1, which is called a truth table for the conditional statement P → Q. greyson ridge charlotte
