As A and B are playing game of 5 points,
As A got 2 points already and B has one one point.
And A and B have equal skills of winning, And A require only 1 point and B require 2 points to win the game.
So the probability of winning next point is equal.
Hence the winning probabilty will depend on previous point gained.
So A has the winning probability of 2/5
