jeff has 8 red marbles, 6 blue marbles, and 4 green marbles that are the same size and shape. he puts the marbles into a bag, mixes the marbles, and randomly picks one marble. what is the probability that the marble will be blue?
Answer
Explanation:
Step1: Calculate total marbles
$8 + 6+4=18$
Step2: Calculate probability of blue marble
The probability $P$ of picking a blue marble is the number of blue marbles divided by the total number of marbles. So $P=\frac{6}{18}=\frac{1}{3}$
Answer:
C. $\frac{1}{3}$
