From a barrel of colored marbles, you randomly select 4 blue, 5 yellow, 6 red, 2 green, and 5 purple marbles. Find the experimental probability of randomly selecting a marble that is not blue.

Answer 1

To find the experimental probability of randomly selecting a marble that is not blue, we need to find the total number of marbles that are not blue and divide it by the total number of marbles in the barrel.

The total number of marbles in the barrel is:

4 blue + 5 yellow + 6 red + 2 green + 5 purple = 22 marbles

The total number of marbles that are not blue is:

5 yellow + 6 red + 2 green + 5 purple = 18 marbles

So the experimental probability of randomly selecting a marble that is not blue is:

18/22 = 0.818 ≈ 82%

Therefore, the experimental probability of randomly selecting a marble that is not blue is approximately 82%.
