Final answer:

The probability of Micki winning is the same as the probability of Talia winning, both are 1/2. Since the chances of winning for both players are equal, the game is considered fair.

Step-by-step explanation:

To determine whether the game with the shoebox of golf balls is fair, we need to calculate the probability of winning for both Micki and Talia. Micki wins if she picks a blue, yellow, or white ball, and Talia wins if she picks a red or green ball. The total number of balls is 40 (10 blue + 16 red + 4 green + 5 yellow + 5 white).

The probability of Micki winning is the sum of probabilities of picking a blue, yellow, or white ball:

Adding these probabilities gives Micki a probability of winning: (10/40) + (5/40) + (5/40) = 20/40 or 1/2.

The probability of Talia winning is the sum of probabilities of picking a red or green ball:

Adding these probabilities gives Talia a probability of winning: (16/40) + (4/40) = 20/40 or 1/2.

Since both Micki and Talia have an equal chance of winning, with a probability of 1/2, this game can be considered fair. Thus, the correct answer to whether the game is fair is: a) Yes, it's fair.
