Question

what are the properties of mathematical expectation​

Answer 1

• Mathematical expectation, also known as the expected value, is the summation or integration of a possible values from a random variable.
• It is also known as the product of the probability of an event occurring, denoted P(x), and the value corresponding with the actual observed occurrence of the event

properties

• an X and Y, then the product of those two random variables are equal to the product of the mathematical expectation of the individual random variables.
• In other words, E(XY)= E(X) E(Y), provided all the expectations exist

Answer 2

Answer:

There are certain properties of mathematical expectation:

The first property is that of the additional theorem. This property states that if there is an X and Y, then the sum of those two random variables are equal to the sum of the mathematical expectation of the individual random variables. In other words,

E(X+Y) = E(X) + E(Y), provided that all the expectations exist.
