Based on these results, what is the expected probability of randomly selecting a ball from the bag in one attempt?
The total number of prizes selected is 30. Out of these 30 selections, a ball was selected 9 times.
Therefore, the probability of randomly selecting a ball from the bag in one attempt can be calculated as:
Probability = Number of times ball was selected / Total number of selections
Probability = 9 / 30
Probability = 0.30 or 30%
Therefore, the expected probability of randomly selecting a ball from the bag in one attempt is 30%.
