So I have a -.8 chance? I think you did your maths a little bit wrong.
The probability for getting the pot of gold at the end of the rainbow is as high as 54% (only if you find the leprachaun).
However, if you voted democrat last election, then the probability increases by 1/3, and if you voted republican then the probability decreases by 2/3.
Behind one door is the pot of gold and behind the other one is nothing. But since the door you first chose is empty by a probability of 1/2, then the probability that the gold is behind the other door is the same, 1/2.
Therefore the chances for me to make fun of your inability to comprehend numbers is -0.8.
Hold on, your were right all along. My bad. Let's bounce homie
