Values of the daily quantity demanded

Reference no: EM13973723

Let S = [O, SJ be a sample space containing all pos sible values of the daily quantity demanded of elec tric power for a large midwestern city in the sum mer months. The units of measurement are millions of megawatts, and the capacity of the power grid is 5 million megawatts.

Answer the following questions concerning proba bility assignments to events in the sample space, S, re lating to the daily demand for electric power. Treat the information provided in the questions as cumulative. Justify your answers.

a. Given that A = (0, 4), B = [3, SJ, P(A) = .512 and P(B) = .784, what is the probability that the power demand will be no greater than 4 million megawatts and no less than 3 million megawatts, i.e., what is the probability of A n B?

b. What is the probability of event C = [O, 3)?

c. Can P(D) = .6, given that D = [O, 2.5)?

d. Given that P([O, 2]) = .064, what is the probability of event E = (2, 4]?
