The thrill of choosing a team to win a game in your bracket and then watching them actually do is unmatched. Roughly 70 million people from around the world fill out March Madness brackets and predict the winners of games. March Madness is a three-week tournament that runs from mid March to early April and features the best 68 teams in division one college basketball. Started in the late 70s, filling out a bracket has become a worldwide phenomenon.

The bracket is laid out in a typical head to head style and is split into four regions. After conference play has finished, there is a selection show on the Sunday before the tournament to determine seeding and schedules. After Selection Sunday, fans go crazy trying to perfect their bracket and do the near impossible; design a perfect bracket.

A perfect bracket is how it sounds and basically means that you would have to guess every game correctly. As if it isn’t hard enough, upsets and unexpected losses make it even more challenging. For example, in the 2018 tournament, the Golden Retreivers That brings up the question, what are the odds of achieving a perfect bracket?

To be blunt, the odds are roughly 1 in 120 billion and that's if you have prior knowledge about college basketball. Without prior knowledge, if you based your predictions simply on the flip of a coin, your odds would skyrocket to 1 in 9.2 quintillion. This means that you are more likely to become President of the United States, die in a vending machine accident, win the mega millions, and win an Oscar. According to many, these odds make the tournament and filling out the bracket even more enjoyable. Nonetheless, it is very difficult but that doesn’t stop those from trying each year.
