Which of the following is a legitimate probability value? 1.67 -0.23 3/2 0.28 16/15 Question 2 of 16 < > 1.25/1.25 = View Policies Show Attempt History v Your answer is correct. Consider the following sample space, S, and several events defined on it. S = {Albert, Betty, Abel, Jack, Patty, Meagan}, and the events are: F = {Betty, Patty, Meagan}, H = {Abel, Meagan}, and P = {Betty, Abell. FU H is empty, since F and H are mutually exclusive empty, since F and H are independent {Meagan} empty, since F and H are complements {Betty, Abel, Patty, Meagan}
