Quizplus · Accepted Answer

The probability of choosing a blue or green marble is the sum of the probabilities of choosing a blue marble and choosing a green marble. There are 15 blue marbles and 30 green marbles, making a total of 45 marbles out of 110. Therefore, the probability is $\frac{45}{110} = \frac{9}{22}$.
