Hi Guys, Im new on here and I need some help. I have been asked this question and i have no idea where to start. Any help would be appreciated.
The joint probability function of two random variables X and Y is given by the following table:
Question 1 : Find the marginal probability function for X.(a) -1, (b) 0, (c) 1.
Question 2 : Find the marginal probability function for Y.(a) -1, (b) 0, (c) 1.
Question 3 : What is the conditional probability that X=1 given that Y=0?
Question 4 : Calculate the mean and variance of X.
Question 5 : Calculate the mean and variance of Y.
Question 6 : Calculate the covariance between X and Y.
Question 7 : Find the correlation between X and Y.
Question 8 : Are X and Y independent?
