Questions

(a) Which stuffed animal is Maya most likely to win?

(b) Which stuffed animal is Maya least likely to win?

(c) Which stuffed animals are equally likely to be won by Maya?

(d) Is it likely that Maya will win an elephant?

(a) Since it is equally likely to pop any balloon, and since there are more balloons with a cat than any other animal, a cat is the most likely stuffed animal to be won.

(b) Since it is equally likely to pop any balloon, and since there are fewer balloons with elephants or pigs than any other animal, an elephant or a pig is the least likely stuffed animal to be won.

(c) Since there are the same number of balloons that contain a bear, a dog, and a rabbit, it is equally likely to win any of these three animals.

(d) Since there are 3 balloons that contain an elephant and 22 balloons that do not contain an elephant, it is not likely that Maya will win an elephant. The probability of winning an elephant is 3/25 or 12%, which is relatively low.
