A group of
N
people wishes to elect one of their members as their leader. Each member of the group can vote for any member in a smaller set of candidates of size
n≤N
. Candidates can vote for themselves. At least
M
votes are needed to elect a leader. Suppose that each of the
N
people votes for one of the
n
candidates randomly. The result shows the approximate probability of election as a function of
n
.
