Imagine an election between two candidates.
A receives m votes, B receives n votes, and A wins (m>n).

If the ballots are cast one at a time, what is the probability that A will lead all the way throughout the voting process?

(In reply to Formula with partial proof by Jer)

Hey!

(m+2)/(m-2)    is    >1

Should be (m-2)/(m+2)
