B)3.3 days
C)10.0 days
D)6.3 days

To estimate the 50% probability, we need to calculate the expected duration using the three estimates provided. One way to find the expected duration is to use the formula:
Expected duration = (best-case + 4 x most likely + worst-case) / 6
Expected duration = (4 + 4 x 6 + 10) / 6 = 6.0 days
Thus, there is a 50% probability that the task will be completed in no more than 6.0 days. Therefore, the best choice is D, 6.3 days, which is the closest to 6.0 days.
