Document Summary
An experiment consists of rolling a pair of dice and observing the. The sample space for this experiment consists of 36 outcomes listed as pairs of numbers: S = {(1, 1), (1, 2), , (6, 6)} Let e be the event that both faces are even and f the event that both faces add to 6. We can easily list the outcomes in f; Those elements of f which are also n e are e f = {(2, 4), (4, 2)}. 1 (c) e f = s (a) e and f are mutually exclusive (b) e f = {(4, 2), (2, 4)} (d) e f = s (e) e f = . {faces sum to 6} is shown in green. {both faces are even} is shown in red. By comparing both pictures we can see that (b) is the only true answer. Let e and f be events where pr(e ) = 4 , and pr(e f ) =
