Question

The joint probability distribution of thr random variables X and Y is given below:

f(x,y) = cxy , 0<x<2 , 0<y<x

0 , other

a.Find the value of the constant.

b.Calculate the covariance and the correlation of the X and Y random variables.

c. Calculate the expected value of the random variable Z= 2X-3Y+2

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
