sasuke is right, thank you :)
Sasuke is right. 100%, thanks :)

This is the whole test i'm doing it for school.

from a barrel of colored marbles, you randomly select 5 blue, 2 yellow, 3 red, 4 green, and 2 purple marbles. Find the experimental probability of randomly selecting a marble that is not yellow.
The total number of marbles is 16, and the number of marbles that are not yellow is 16 - 2 = 14. Therefore, the experimental probability of randomly selecting a marble that is not yellow is 14/16, or 7/8.
To find the experimental probability of randomly selecting a marble that is not yellow, we need to determine the total number of marbles that are not yellow and the total number of marbles in the barrel.
First, let's calculate the total number of marbles that are not yellow. In this case, we have 5 blue, 3 red, 4 green, and 2 purple marbles. So, the total number of marbles that are not yellow is:
Total marbles that are not yellow = 5 (blue) + 3 (red) + 4 (green) + 2 (purple) = 14 marbles
Next, we need to calculate the total number of marbles in the barrel, which includes both yellow and non-yellow marbles. From the information given, we have:
Total marbles in the barrel = 5 (blue) + 2 (yellow) + 3 (red) + 4 (green) + 2 (purple) = 16 marbles
Now we can find the experimental probability of randomly selecting a marble that is not yellow by dividing the total number of marbles that are not yellow by the total number of marbles in the barrel:
Experimental probability of selecting a marble that is not yellow = Total marbles that are not yellow / Total marbles in the barrel
= 14 / 16
= 7 / 8
≈ 0.875
Therefore, the experimental probability of randomly selecting a marble that is not yellow is approximately 0.875, which is equivalent to 87.5%.
Sasuke is right (Kinda i guess) i missed a question but not his fault.
I think you are taking 1 marble from a barrel that contains the ones you have stated. Right?
there are 16 marbles
14 are not yellow
14/16 = 7/8
