Question

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? $\frac{2}{9}$ $\frac{1}{3}$ $\frac{4}{9}$ $\frac{1}{2}$

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:

$\frac{1}{3}$
