What was the experimental probability of choosing a blue marble from a bag?

The answer would be 7/20. Because when it said you did that a total of 20 times. And then you would just put how many times you pulled a blue over it.

The experimental probability of choosing a blue marble from a bag is 7/20.

What is Experimental Probability?

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

Total number of trials is 20.

Number of trial in which we get blue ball is 7.

According to definition,

Experimental probability = [tex]\frac{Number of times}{total number of times}[/tex]

P = 7/20.

Thus, the experimental probability of choosing a blue marble from a bag is 7/20.
