Question

use the following information for problems 3 and 4.

From a barrel of colored marbles, you randomly select 7 blue, 5 yellow, 8 red, 4 green, and 6 purple marbles.


Find the experimental probability of randomly selecting a marble that is not yellow. Write your answer in simplest form.
A. start fraction 1 over 30 end fraction
B. five-sixths
C. start fraction 2 over 15 end fraction
D. start fraction 1 over 6 end fraction

Answer 1

There are a total of 7 + 5 + 8 + 4 + 6 = 30 marbles. Out of these, 5 are yellow and the rest (30 - 5 = 25) are not yellow. So, the experimental probability of randomly selecting a marble that is not yellow is:

25/30

Simplifying, we get:

5/6

Therefore, the answer is B. five-sixths.
