Based on these results, what is the expected probability of randomly selecting a ball from the bag in one attempt?
To calculate the expected probability of randomly selecting a ball from the bag in one attempt, we first need to determine the total number of selections made (30) and the number of times a ball was selected (9).
The expected probability can be calculated as follows:
Expected probability = Number of times a ball was selected / Total number of selections
Expected probability = 9 / 30
Expected probability = 0.3
Therefore, the expected probability of randomly selecting a ball from the bag in one attempt is 0.3 or 30%.
