For each of the following pairs of events, tell whether they are disjoint, independent, or neither. a. A = {8 on the first roll }, B = {8 or more on the first roll }. b. A = {8 on the first roll }, B = {8 or more on the second roll }. C. A = {6 or less on the second roll }, B = {6 or more on the first roll }. d. A = {4 or less on the second roll }, B = {6 or less on the second roll }
