Question

PROBLEM 09: A random variable X has the density function below, where y and p are unknown numbers. If E[X] = 2.9, what are the values of p and y? Values of X Pr{ x = x] 0.2 0.5 A) p = 0.3, y = 4.4 D) p = 0.3, y = 6.0 B) p = 0.3, y = 5.6 E) p = 0.4, y = 5.8 C) cannot be determined because there is not N) none of the above (which means that the answer enough information given in the problem. can be determined, but it is not listed among the answer choices given).
