Question

A bag with 12 marbles has 3 red marbles and 5 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is red?

Answer 1

The probability that it is red would be 1/4

Answer 2

3/12 = 1/4

Explanation:

There are 12 marbles in the bag. If the marble drawn at random is red, it is one of the 3 red marbles.

The probability is "3 out of 12" = 3/12 which simplifies to 1/4.
