Question

What is the sum of the probability distribution of random variable y?

Answer 1

Step-by-step explanation:

In many applications, we need to work with a sum of several random variables. In particular, we might need to study a random variable Y given by

In many applications, we need to work with a sum of several random variables. In particular, we might need to study a random variable Y given byY=X1+X2+⋯+Xn.

In many applications, we need to work with a sum of several random variables. In particular, we might need to study a random variable Y given byY=X1+X2+⋯+Xn.The linearity of expectation tells us that

In particular, we might need to study a random variable Y given byY=X1+X2+⋯+Xn.The linearity of expectation tells us thatEY=EX1+EX2+⋯+EXn.We can also find the variance of Y based on our discussion in Section 5.3. In particular, we saw that the variance of a sum of two random variables is
