In Ping-Toss, the object is to toss two Ping-Pong balls so they each land in a red section of the stick-em board. Phil's first toss landed in a red section. How does his chance of winning change if he is allowed to remove the first ball before he tosses the second?

It increases, because if the first ball is left in a red section, there is less red area for the second ball to land on. - trust

It depends on how you view it.

Essentially, one person might argue that he has a better chance because he has more room to land the ball in the red, but others might argue that it has no true effect. I believe it increases his chances of winning because of the ability to land the ball in the red.
