Question

Jim's marble collection contains 20 marbles, including 4 pink marbles. What is the probability that a randomly selected marble will be a pink marble? Write your answer as a fraction or whole number.

Answer 1

Answer: 20%

Explanation:

The probability that a randomly selected marble will be pink can be found by the formula:

= Number of pink marbles / Number of total marbles

= 4 / 20

= 20%

There is a 20% chance that if you pick a marble, it will be pink.
