4. A weighted die has a probability of a 6 being p where 0 < p < 1. Chrisrolls 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 twotosses. Find the population covariance between X and Y. Interpret themeaning of the value in context of the problem.

The probability of 6 coming up on the weighted die is p. The die is rolled 3 times. The random…
