In the weighted voting system below, the weights represent voters \( A, B, C \), and so on, in that order. Find the critical voter(s) in the winning coalitions. \( [14: 1,4,6,8] \) In all the winning coalitions \( \{C, D\},\{A, C, D\},\{B, C, D\} \), and \( \{A, B, C, D\} \), who is(are) the critical voter(s)? A and B C and D D C

Weights: A = 1, B = 4, C = 6, D = 8 with a quota of 14. Let's check each listed winning coalition: 1. Coalition {C, D}:  Total = 6 + 8 = 14.  • Removing C: 8 (loses)  • Removing D: 6 (loses)  So both C and D are critical. 2. Coalition {A, C, D}:  Total = 1 + 6 + 8 = 15.  • Removing A: 6 + 8 = 14 (still winning), so A is not critical.  • Removing C: 1 + 8 = 9 (loses)  • Removing D: 1 + 6 = 7 (loses)  Thus, C and D are critical. 3. Coalition {B, C, D}:  Total = 4 + 6 + 8 = 18.  • Removing B: 6 + 8 = 14 (still winning), so B is not critical.  • Removing C: 4 + 8 = 12 (loses)  • Removing D: 4 + 6 = 10 (loses)  Again, C and D are critical. 4. Coalition {A, B, C, D}:  Total = 1 + 4 + 6 + 8 = 19.  • Removing A: 4 + 6 + 8 = 18 (still winning), so A is not critical.  • Removing B: 1 + 6 + 8 = 15 (still winning), so B is not critical.  • Removing C: 1 + 4 + 8 = 13 (loses)  • Removing D: 1 + 4 + 6 = 11 (loses)  So, C and D are critical. In every winning coalition, the critical voters are C and D. The answer is: C and D.
