Question #8

On a certain soccer team, one team member is to be chosen at random to play in the goalie position. What is the probability that a girl will be chosen?

(1) One-quarter of the team members are girls.

(2) 16 of the team members are boys.

Explanation

Since 1/4 of the team members are girls, the probability of a girl being chosen would be 1/4. Thus, statement (1) is sufficient. Statement (2) is no good because we wouldn’t know the total number of teammates. Without that information, we can’t use the number of boys on the team alone to determine the probability. Statement (2) is NOT sufficient. The correct answer is (A).
