Ultimately, everything in the universe boils down to this. The chances of any event happening are exactly 50/50 Every event. Every time. No. Matter. What. As I am sitting here, I am wondering if a meteor will hit my house. I wonder what the chances of this occurring are. Well now I know. The chances are 50/50 A meteor either will hit my house, or it will not 50/50 It either will happen, or it will not happen. There is not a single thing or event that this does not apply to.
