In the example with the prize wheel, there was only one option that gave you the biggest chocolate. Yet, there were three other fields on the wheel that would have given you smaller chocolates. What is the probability that you get a chocolate as a prize regardless of its size?
The numerator must be the number of outcomes that give you a prize. There are four fields on the wheel that give you a prize: One field wins you the big chocolate, and three fields win you smaller chocolates. Therefore, it should say 4 in the numerator.
The denominator must state how many possible outcomes there are. There are still 12 different fields that can stop under the pin. Therefore, it should say 12 in the denominator. The probability of winning a chocolate prize (small or large), is then .
