How to play the animation after it has been rendered? I'm pretty new to Blender and I followed a tutorial online to create an animation.

I finished the building of the animation and it told me to render the animation. So I rendered it and waited 24 hours before it was done. When the render was completed, I tried to click the play button and it showed that it was going through all of the frames but the animation wasn't playing. I'm wondering if anyone can tell me how to get the animation to play?
To play the Rendered Animation Click Ctrl+F11 

Or :
Select "Play  Rendered  Animation " from Render menu :
