Suppose you have a large bag of plain M&M candies and you choose one candy at random.
(a) Find P(green candy or blue candy).

P(green candy or blue candy) means the probability that you pick a green or a blue one.

For either-or probability, add the individual probabilities.

18% is the answer.

To find the probability of getting a green candy or a blue candy from the bag of M&M candies, you need to add the percentages of green candies and blue candies.

According to the given information, the percentage of green candies is 9% and the percentage of blue candies is also 9%.

To find the probability, you add these percentages together:

P(green candy or blue candy) = P(green candy) + P(blue candy)
= 9% + 9%
= 18%

Therefore, the probability of selecting a green candy or a blue candy from the bag is 18%.
