Why does a rubber ball float in water?

This might be best determined by experiment. While natural rubber is slightly denser than water and will sink, there will be some small amount of air trapped in a rubber band ball, reducing the density to some extent. Attempting to model and calculate the air content seems somewhat impractical without experimental data, and if you are going to experiment anyway, why not just find the answer directly?

Why does a ball float and a stone sink?

Something will sink if it is heaver than the same volume of water, so it depends on the density of the ball. Rock is denser than water so stones sink. However, depending on what a ball is made of it may or may not be heavier than the same volume of water. For example a golf ball is denser than water so it sinks, but a ping-pong ball is lighter and will float.
