A A B B Sleeping Pill Experiment Vaidman (1998) ISPS 0.9 0.1 Ignorance probability of the descendents A and B
Only and can give this answer 0.9 What is the probability that you are in A? 0.9 A A B 0.9 0.1 What is the probability that you are in A? B
0.9 0.9 What is the probability that you are in A? What is the probability that you are in A? 0.9 A A B 0.1 B Since all the descendents yield the same answer we can relate it to me before the experiment. I put my bet for the descendents. They have probability. Thus, my bet is for a probabilistic event. This is the ignorance probability meaning of the measure of existence. .
