P(M) > 1

Typo?

If observing a dead cat causes the waveform to collapse such that the cat is dead, then P(D) = P(D) + P(M)(1-P(D)).  This is possible only if P(D) = 1.

Sorry if I'm missing something, but are you implying that the Copenhagen interpretation implies that the waveform collapse happens so as to retroactively make the cat dead if Schrödinger would have mistaken the cat for dead? Why would the sort of model that forms in Schrödinger's brain after the fact control what did in fact happen, even given the Copenhagen interpretation? (I didn't think it was quite that silly.)

Typo.

I'm going to add my comment reply (below) to the post, in response to your question.
