Question

A jar contains 8 red marbles, 10 blue marbles, and 2 yellow marbles. One marble is chosen at random. The color is recorded in the table and then it is returned to the jar. This is repeated 40 times. What is the experimental probability of choosing a yellow marble? Express your answer as a percent to the nearest whole number.

RED/14 BLUE/16 YELLOW/10

Answer 1

• 1/4 or 25%

Explanation:

Experimental probability:

• Pe = number of event occurred / number of attempts

Probability of yellow:

• Pe(yellow) = 10/40 = 1/4 = 25%
