Where did the 3:1 ratio come from? I know the decay rate of the radioactive source. I can arrange to open the box when there is only a 10% chance that the atom has decayed. In that case I clearly have a 90% chance of seeing a live cat when I open the box. Similarly, I can arrange for any probability between zero and one of seeing a live cat. Whereas, if there is always a live cat branch and a dead cat branch, my probability of seeing a live cat is always 50%, contrary to the laws of radioactive decay.
