The random experiment consists of throwing two fair dice. Let us define the events: D = {the sum of the dice equals 6} E = {the sum of the dice equals 7} F {the first die lands 4} %3D {the second die lands 3} Show the following, both by arguing and by computing probabilities: (a) D is not independent of F and D is not independent of G. (b) E is independent of F and E is independent of G. (c) E is not independent of (F, G), in fact, E is completely determined by (F,G). (Here is an example where an event is independent of each of two other events but is not independent of the joint occurrence of these events.)
