A jar contains 10 red marbles, 6 blue marbles, 8 green marbles, and 4 yellow marbles. One marble is randomly drawn. What is the probability that either a yellow marble or a blue marble is drawn?
A)4/14
B)1/7
C)9/14
D)5/14
The probability of drawing a yellow marble is 4/28 and the probability of drawing a blue marble is 6/28. Adding these probabilities together gives 4/28 + 6/28 = 10/28 = 5/14.
Therefore, the correct answer is:
D) 5/14
