Answer #1

Answer: 7.5

Explanation:

Given optimistic time estimate, o = 3 days

Most likely time estimate, m = 8 days

Pessimistic time estimate, p = 10 days

Expected time for the activity, Te = [o + 4m + p]/6

                                             = [3+ (4 x 8) + 10] / 6 = 7.5 days

Hence the answer is second option, 7.5
