Explanation
To find the expected time (TE) and variance for the activity, use the PERT formulas: TE = (Optimistic + 4 × Most Likely + Pessimistic) / 6 and Variance = ((Pessimistic - Optimistic) / 6)². Substituting the values: TE = (2 + 4×3 + 7) / 6 = 5, and Variance = ((7 - 2) / 6)² = (5/6)² = 25/36.
