4. Independent events are events which have no effect whatsoever on the probability of each other happening. If A and B are independent, then whether or not A happens has NO effect on P(B). If A and B are independent then P(A and B) = P(A)  P(B). Eg When rolling a red die and rolling a green die. What happens on one die has no effect on the outcome of the other die. P(6 on Red die) = 1/6 P(6 on Green die) = 1/6 P(6 on Red Die given that there was a 6 on the Green die) = 1/6 (Note: we can denote the above as P(6 on red | 6 on green). This thing

Some of the earlier exercises are very straightforward (but do make sure you can work up a sample space in any situation) and the later ones get quite complex so make so you spend a reasonable amount of time on them.
