To find the weight of the coalition \(\{P_2, P_3, P_4\}\) in the weighted voting system \([14: 8, 5, 4, 2, 1]\), we need to sum the weights of \(P_2\), \(P_3\), and \(P_4\).
Given the weighted voting system \([14: 8, 5, 4, 2, 1]\), we need to find the weights of the coalition \(\{P_2, P_3, P_4\}\). The weights of \(P_2\), \(P_3\), and \(P_4\) are 5, 4, and 2, respectively.
To find the total weight of the coalition \(\{P_2, P_3, P_4\}\), we sum the individual weights:
\[
\text{Weight} = 5 + 4 + 2
\]
Perform the addition:
\[
\text{Weight} = 5 + 4 + 2 = 11
\]
