Newton's third law states that for every action there is an equal and opposite reaction. How does this apply to everyday life? An example would be that if you bounce a ball on the ground it will come back up, but how is this an EQUAL and opposite reaction? Can anyone give me a better example and explain this one?

Lets say you push on a wall. Why don't you go through it. The wall is actually pushing back on you with an equal force. You just don't notice this.
For another example, lets say you push a box to the right. A frictional force will go to the left, and the rest will be converted into kinetic energy. (movement). If you relate these forces and energies together in an equation, they will be equal.
Here's a simpler explanation. Back to the wall, lets say you punched it instead of pushed it. Why does it hurt your hand? Because the wall pushed back with an equal force.
As for the ball, there are other factors such as gravity in play.
Hope this helps explain it a little more.

EXAMPLE AT BOTTOM
"To every action there is always an equal and opposite reaction: or the forces of two bodies on each other are always equal and are directed in opposite directions. ”
A more direct translation than the one just given above is:
“ LAW III: To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts. — Whatever draws or presses another is as much drawn or pressed by that other. If you press a stone with your finger, the finger is also pressed by the stone. If a horse draws a stone tied to a rope, the horse (if I may so say) will be equally drawn back towards the stone: for the distended rope, by the same endeavour to relax or unbend itself, will draw the horse as much towards the stone, as it does the stone towards the horse, and will obstruct the progress of the one as much as it advances that of the other. If a body impinges upon another, and by its force changes the motion of the other, that body also (because of the equality of the mutual pressure) will undergo an equal change, in its own motion, toward the contrary part. The changes made by these actions are equal, not in the velocities but in the motions of the bodies; that is to say, if the bodies are not hindered by any other impediments. For, as the motions are equally changed, the changes of the velocities made toward contrary parts are reciprocally proportional to the bodies. This law takes place also in attractions, as will be proved in the next scholium
EXAMPLE:
The Third Law means that all forces are interactions between different bodies, and thus that there is no such thing as a unidirectional force or a force that acts on only one body.
(If two skaters are pushing against eachother) Newton's third law. The skaters' forces on each other are equal in magnitude, but act in opposite directions.

For example, the force of gravity is pulling you down yet the normal force (surface) pushes you upwards.
Another example of that would be if you picture an astronaut that can't reach his spaceship during his or her space walk. Picture that astronaut throwing a ball in the opposite direction. And as he/she does that, there will be an opposite yet equal reaction which means that the astronaut will be pushed in the opposite direction towards the spaceship.
Hope that helps :-}

No your occasion isn't incorrect for Newton's 0.33 regulation of action. there is one action in contact: ball hitting the wall, and one reaction: wall inflicting the ball to bounce back. The reaction is in opposite process action. besides the action tension and the reaction tension are co-linear, that's, horizontal (assuming the wall is vertical).
