Question

a bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. what is the probability of drawing a green marble?

Explanation:

Step1: Calculate total marbles

$5 + 3 + 2 = 10$

Step2: Find green marble probability

$\text{Probability} = \frac{\text{Number of green marbles}}{\text{Total number of marbles}} = \frac{2}{10} = \frac{1}{5}$

Answer:

$\frac{1}{5}$ or 0.2
