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.
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%.
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.
First, let's find the total number of marbles that are not blue. We have:
Yellow marbles: 5
Red marbles: 6
Green marbles: 2
Purple marbles: 5
So, the total number of marbles that are not blue is 5 + 6 + 2 + 5 = 18.
Now, let's find the total number of marbles we have in the barrel. We have:
Blue marbles: 4
Yellow marbles: 5
Red marbles: 6
Green marbles: 2
Purple marbles: 5
So, the total number of marbles is 4 + 5 + 6 + 2 + 5 = 22.
Finally, we can find the experimental probability by dividing the number of marbles that are not blue by the total number of marbles:
Experimental probability = (number of marbles that are not blue) / (total number of marbles)
Experimental probability = 18 / 22
Therefore, the experimental probability of randomly selecting a marble that is not blue is 18/22, which can be simplified to 9/11.
