(3) Find the density of the random variable X representing the number of correctly placed letters when n = 4 letters are randomly placed into the four envelopes. The following answers are proposed for the density, I Values of X 0 1 P1 2 3 4 P2 P3 P4 Probabilities Po where • P1 = P2 = P3 = 0, p4 = . Pa = 0, p4 = 4. P4 = (a) Po = (b) Po = Pi = 7. P2 3. PI=. Pa = (d) po = PI = P2 = (e) None of the above (c) Po = Pa P4 = Then correct answer is: (a) (b) (c) (d) (e) N/A (Select One)
