From a barrel of colored marbles, you randomly select 6 blue, 4 yellow, 2 red, 3 green, and 5 purple marbles. Find the experimental probability of randomly selecting a marble that is not yellow.
The total number of marbles is:
6 blue + 4 yellow + 2 red + 3 green + 5 purple = 20 marbles
The number of marbles that are not yellow is:
6 blue + 2 red + 3 green + 5 purple = 16 marbles
Therefore, the experimental probability of randomly selecting a marble that is not yellow is:
number of marbles that are not yellow / total number of marbles = 16/20 = 0.8
This can also be expressed as a percentage:
0.8 x 100% = 80% chance of selecting a marble that is not yellow.

To find the experimental probability of randomly selecting a marble that is not yellow, we need to determine the number of marbles that are not yellow and divide it by the total number of marbles.
The number of marbles that are not yellow is the sum of all the marbles of different colors, excluding the yellow marbles.
So, the number of non-yellow marbles = number of blue marbles + number of red marbles + number of green marbles + number of purple marbles
= 6 + 2 + 3 + 5
= 16.
Now, we need to divide this value by the total number of marbles to get the experimental probability.
The total number of marbles = number of blue marbles + number of yellow marbles + number of red marbles + number of green marbles + number of purple marbles
= 6 + 4 + 2 + 3 + 5
= 20.
Therefore, the experimental probability of randomly selecting a marble that is not yellow is:
Number of non-yellow marbles / Total number of marbles
= 16 / 20
= 0.8.
So, the experimental probability of randomly selecting a marble that is not yellow is 0.8 or 80%.
To find the experimental probability of randomly selecting a marble that is not yellow, we need to calculate the number of marbles that are not yellow and divide it by the total number of marbles.
In this case, we have:
Blue marbles: 6
Yellow marbles: 4
Red marbles: 2
Green marbles: 3
Purple marbles: 5
To find the number of marbles that are not yellow, we sum up the marbles of all other colors:
Non-yellow marbles = blue marbles + red marbles + green marbles + purple marbles
Non-yellow marbles = 6 + 2 + 3 + 5 = 16
The total number of marbles is the sum of marbles of all colors:
Total marbles = blue marbles + yellow marbles + red marbles + green marbles + purple marbles
Total marbles = 6 + 4 + 2 + 3 + 5 = 20
Now, we can calculate the experimental probability of randomly selecting a marble that is not yellow:
Experimental probability = Number of non-yellow marbles / Total number of marbles
Experimental probability = 16 / 20
Therefore, the experimental probability of randomly selecting a marble that is not yellow is 16/20, which can be simplified to 4/5 or 0.8.
