Answer:
P(choosing a blue, green, or yellow chip) = 100%, or 1
Explanation:
You are finding the probability of getting either one blue, or green, or yellow chip. Note that there are only blue, green, and yellow chips, and if you are forced to choose from the pile, you can only get those types. This makes it so that you are most certainly getting what the probability is asking for, making it 100% chance.
