Question The table shows the results of randomly selecting colored marbles from a bag 36 times. The marble was returned to the bag after each selection. White Red Black Blue Number of Times Selected 8 14 9 5 Based on these results, what is the expected probability of randomly selecting a black marble from the bag in one attempt? Responses A 0.1390.139 B 0.220.22 C 0.250.25 D 0.9
To find the expected probability of randomly selecting a black marble from the bag, you would divide the number of times a black marble was selected by the total number of selections:
9 (number of times black marble was selected) / 36 (total number of selections) = 0.25 or 25%
Therefore, the expected probability of randomly selecting a black marble from the bag in one attempt is C) 0.25 or 25%.
