Answer: The answer is {(w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l), (l, w, w)}.
Step-by-step explanation: Given that a person in the casino is going to play 3 games of blackjack. Here, 'w' denotes a win and 'l' denotes a loss.
Also, let 'A' be the event that the person wins at least one game of blackjack. Then, the outcomes of Event 'A' are
(i) win in 1st game loss in 2nd game loss in 3rd game
(ii) win in 1st game win in 2nd game loss in 3rd game
(iii) win in 1st game loss in 2nd game win in 3rd game
(iv) win in 1st game win in 2nd game win in 3rd game
(v) loss in 1st game loss in 2nd game win in 3rd game
(vi) loss in 1st game win in 2nd game loss in 3rd game
(vii) loss in 1st game win in 2nd game win in 3rd game
Thus, the outcomes of the event A are (w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l) and (l, w, w).
Thus, A = {(w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l), (l, w, w)}.
