Answer: The correct option is
(D) {WWW, WWL, WLW, WLL, LWW, LWL, LLW}.
Step-by-step explanation: Given that a person in a casino decides to play 3 games of blackjack.
Here , W denote a win and L denote a loss.
Event A is defined as "the person wins at least one game of blackjack".
Since the person is playing 3 games, so the sample space of the experiment is given by
S = {WWW, WWL, WLW, WLL, LWW, LWL, LLW, LLL}.
Since, according to event E, the person wins at least one game, so the element LLL will not be there.
Therefore, the elements of event E are WWW, WWL, WLW, WLL, LWW, LWL, LLW.
Thus, the possible outcomes of E are {WWW, WWL, WLW, WLL, LWW, LWL, LLW}.
Option (D) is CORRECT.
