A bag contains 3 red, 6 blue, 5 purple, and 2 orange marbles. One marble is selected at
random. What is the probability that the marble chosen is blue? Answer with a
percentage or a simplified ratio.
b. The probability of choosing a blue marble is blue/total.The number of blue marbles is 6, and the total number of marbles is 16 (3 + 6 + 5 + 2 = 16).Therefore, the probability of choosing a blue marble is 16/16 = 3/8.
