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. (1 point)
There are a total of 4 + 5 + 6 + 2 + 5 = 22 marbles.
The probability of selecting a blue marble is 4/22.
The probability of selecting a marble that is not blue is 1 - 4/22 = 18/22 = 9/11.
Therefore, the experimental probability of randomly selecting a marble that is not blue is 9/11.
To find the experimental probability of randomly selecting a marble that is not blue, we need to find the total number of non-blue marbles and divide it by the total number of marbles.
The total number of marbles is given by:
Total marbles = 4 (blue) + 5 (yellow) + 6 (red) + 2 (green) + 5 (purple) = 22
The number of non-blue marbles is given by:
Non-blue marbles = Total marbles - Blue marbles = 22 - 4 = 18
Therefore, the experimental probability of randomly selecting a marble that is not blue is:
Experimental probability = Non-blue marbles / Total marbles = 18 / 22
Simplifying this fraction, we get:
Experimental probability = 9 / 11
So, the experimental probability of randomly selecting a marble that is not blue is 9/11.
