Threeway ball toss

Discrete Mathematics Level pending

Adam, Ben, and Charles decide to play a game of toss. Adam starts with the ball. A toss consists of one player passing the ball to any of the other two players. After one toss, the probability that Adam has the ball is zero and the probability that Ben or Charles have the ball is a half. If the person selected to receive the ball is randomly selected for each toss, then after what toss yields the greatest probability that Adam will have the ball again?
