@Lana With an electorate of 15,135 voters, and assuming toss up conditions, the chance of a single vote decision is 0.065%. Use the BINOMDIST spreadsheet function to play around with the chances of single vote decisions with respect to electorate size. It diminishes as the electorate size increases, but especially as you move away from toss-up conditions (with any given voter being slightly more or less likely to vote for a candidate than not).
