4. A weighted die has a probability of a 6 being p where 0 < p < 1. Chris rolls the die 3 times. Let X be the number of times 6 appears on the die. Z is the number of times any number other than 6 appears on the last two tosses. Find the population covariance between X and Y. Interpret the meaning of the value in context of the problem.
