Question

A bag contains 2 red marbles, 3 green
marbles, and 2 black marbles. What is the
probability of drawing out (without looking) a
black marble? Write your answer as a fully
reduced fraction.

Answer 1

Answer:

2/7 ≈ 28.6%

Explanation:
There are two black marbles in the bag and seven marbles in total, therefore you have a chance of two out of seven to get a black marble.
