The expected probability of randomly selecting a ball from the bag can be calculated by dividing the number of times the ball was selected by the total number of selections, which is 30.
Expected probability = Number of times selected / Total number of selections
Expected probability = 9 / 30
Expected probability = 0.30
Therefore, the expected probability of randomly selecting a ball from the bag in one attempt is 0.30.
