Question

You randomly draw a marble from a bag of marbles that contains 3 blue marbles, 4 green marbles, and 5 red marbles. What is P(draw a blue marble)? If necessary, round your answer to 2 decimal places

Answer 1

Answer:

P(blue) = .25

Step-by-step explanation:

We need to know how many marbles in the bag

3 blue marbles+ 4 green marbles+ 5 red marbles = 12 marbles

P ( blue) = blue / total = 3/12 = 1/4 = .25
