Based on these results, what is the expected probability of randomly selecting a black marble from the bag in one attempt?
Responses
The expected probability of randomly selecting a black marble from the bag in one attempt can be calculated by dividing the total number of times the black marble was selected (9) by the total number of selections made (36).
So, the expected probability is 9/36 = 1/4 = 0.25 or 25%.
