1. A random variapie can assume five (5) values: 0, 1, 2, 3, 4. A portion of the probability distribution is shown here. (3 items x 2 points) P(X = x) 3 a Find P(X = 3). b. What is the probability that x is greater than 2? c. What is the probability that x is 3 or less? 2. The following table is a partial probability distribution for the MRA Company's projected profits (x-profit in P1000s) for the first year of operation ( the negative value denotes a loss). (2 items x 2 points) -100 10 20 50 100 30 25 150 200 10 a. What is the proper value for f(200)? What is your interpretation of this value? b. What is the probability that MRA will be profitable? 1.
