In a certain game only one player can win and only one player always eventually wins. James, Austin, and Katelyn play this game together 3 times in a row. What is the probability that Katelyn wins at least one of the 3 games.?
(1) The probability that either James or Austin wins the game is 3/4
(2) James and Katelyn have an equal probability of winning the game.
OA is A
Given: Only one player can and only one eventually wins. J,A, and K play this game 3 times in a row.
Question: P(K wins at least one of the 3 games) = 1 - P(K wins none of the 3 games)
(1) P(K doesn't win) = 3/4
P(wins at least one of the 3 games) = 1 - (3/4 * 3/4 * 3/4)
Sufficient
(2) I am not sure why this is statement is not sufficient
J and K have an equal probability of winning the game. They play 3 games together. So, the
P(K wins) = 1/3
P(J wins) = 1/3
P(A wins) = 1/3
So, here i can figure out the probability that P(K wins at least one of the three games)
Not sure where i am wrong.
