Question

A bag contains 3 red marbles and 2 blue marbles.

What is the probability of reaching in and pulling out a red marble? Write your answer as a fraction, decimal and a percent.

Answer 1

3/5; 0.6; 60%

Explanation:

There are 3 red marbles, and 2 blue marbles. Add them together, and you get 5. You want to know how likely it will be to pull out a red marble, so the chance is 3 out of 5 (3/5). To get a decimal, you divide 3 by 5, and you get 0.6, and to make it a percent, move the decimal to the right twice or do 0.6 *100 and you get 60%.

Answer 2

3/5 = 0.6 = 60%

Explanation:

There are total:

• 3 + 2 = 5 marbles in the bag

• 3 out of them are red

Probability of pulling out a red is three out of five:

• 3/5 = 0.6 = 60%
