1. You have a bag containing 12 red marbles, 8 blue marbles, and 16 yellow marbles. You select one at random. What is the probability you select a blue marble?
A. 1/3
B. 2/9
C.4/9
D.1/2
B. 2/9
Explanation: There are 8 blue marbles out of a total of 12 red, 8 blue, and 16 yellow marbles. So, the probability of selecting a blue marble is 8 out of 12 + 8 + 16 = 32 marbles, which simplifies to 8/32 = 2/9.
