Not the same comparison. The If it is incurable, the chance of death is 100% if no action is taken.
When you go into surgery, the surgeon is careful to mention that there are no guarantees, and that you may die as a result of invasive procedures. But you get your gall bladder taken out, anyway.
Would you go to a surgeon that would give you a 77% chance that at the end of the surgery he would not have removed your gall bladder?
If it was 77% probable that I would die because of surgery, and 100% probable that I would die without it, sure I'd take the surgery.
That's not a very subtle argument.
It's been fun. Gotta go. CYa
