So I did a little experiment. I looked up the schedule for the day's baseball games and randomly chose someone to win for 14 games (and I know baseball like I know the mating habits of unicorns so no bias). If you randomly guess on a coin toss each toss, you should be right 50% of the time and wrong the other 50% (or close to that) because it is 50/50. I flipped a coin 98 times with 7 trials of 14 flips as a control; six of the trials ended in 6 heads/tails to 8 and the other was exactly 7 to 7. Now, when I got the results of the baseball games, this distribution did not occur. For this, it was 10 to 4.
So, statistically it seems even guessing isn't 50/50. Also, I'm doing another trial today with the day's football games.
