User:Steve Smith/50% plus .5

In groups whose size is a natural number, 50% + .5 is synonymous with simple majority. 50% + 1 is often incorrectly held to represent a simple majority, but this is true only for even numbers.

Proof
Let size of group = 11 50% of 11 = 5.5 50% + 1 of 11 = 6.5 6 < 6.5 Therefore, if 50% + 1 were equal to a simple majority, 6 would not be a majority of 11.
