Based on these results, what is the expected probability of randomly selecting a ball from the bag in one attempt?
To find the expected probability of randomly selecting a ball from the bag in one attempt, we need to divide the number of times the ball was selected by the total number of selections.
In this case, the ball was selected 9 times out of 30 selections. So, the expected probability of randomly selecting a ball from the bag in one attempt is:
9 / 30 = 0.3
Therefore, the expected probability of randomly selecting a ball from the bag in one attempt is 0.3 or 30%.
wrong
I apologize for the mistake. To find the expected probability of randomly selecting a ball from the bag in one attempt, we need to divide the number of times the ball was selected by the total number of selections of all prizes.
The total number of selections for all prizes is 30.
The ball was selected 9 times.
To find the expected probability of selecting a ball, we calculate:
P(selecting a ball) = Number of times ball was selected / Total number of selections
P(selecting a ball) = 9 / 30
P(selecting a ball) = 0.3
Therefore, the expected probability of randomly selecting a ball from the bag in one attempt is 0.3 or 30%.
