articular unfair coin is constructed so that the probability of obtaining a head is 1/3. The ir coin is flipped twice. Define two random variables: Z = the number of heads in the flip and W = the number of heads in two flips. i. Construct a table showing the joint probability distribution of both random variables Z and W including the marginal probabilities. ii. Find the covariance between Z and W. Are they independent? iii. Suppose the covariance between Z and W were 0. Would this imply that Z and W
