I'm trying to work out genetic probabilities using the punnet square.
Let's say I have 2 shirts and 2 pants. The odds of me wearing shirt #1 is 1/2. The odds of me wearing pants #1 is 1/2. Does this mean that the odds of me wearing shirt #1 or Pants #1 is 1 (100%) (addition rule - 1/2 + 1/2). This seems counterintuitive.
Is the answer that I have to subtract out from 100% the odds of me wearing BOTH shirt #1 and pants #1?
Thanks
