Section A, Question 1 Step 1: Standard value of ()/(3). ()/(3) = sqrt(3)2 Step 2: Standard value of ()/(3). ()/(3) = (1)/(2) Step 3: Add the values. ()/(3) + ()/(3) = sqrt(3)2 + (1)/(2) = 1 + sqrt(3)2 1 + sqrt(3)2 Section A, Question 2 (Men work problem) Step 1: Total man-days required for the wall. 30 men × 20 days = 600 man-days. Step 2: Days taken by 25 men. Days = (600)/(25) = 24 days. 24 days Section B, Question 1 (Probability of two tails) Step 1: Probability of tails on single fair coin toss. P(tail) = (1)/(2) Step 2
