There are three green balls and four yellow balls in a sack. Mary picks two balls from the sack. If she has done this thirteen times (assuming she places the balls back into the sack), with seven of the outcomes resulting in one green ball and one yellow ball, two of the outcomes resulting in two green balls, and four of the outcomes resulting in two yellow balls. Which of the following is true for her fourteenth trial.

It is impossible to determine the likeliness of any possible outcome Mary is more likely to pick two balls of the same color than two balls of different color Mary is more likely to pick two balls of different color than two balls of the same color Mary is guaranteed to pick two balls of different color
