Sleeping Beauty problem: Difference between revisions

Sleeping Beauty volunteers to be put into a deep sleep on a Sunday. There is then a fair coin toss.

If this coin toss comes up heads, Sleeping Beauty wakes once (on Monday) and asked to

then put back to sleep for 2 days until Wednesday, at which time the experiment's results are tallied.

If instead the coin toss is tails, Sleeping Beauty wakes as before on Monday and asked to

later, on Tuesday. She is then asked (on Tuesday) again to guess the probability that the coin toss

was heads or tails. She is then put back to sleep and awakes as before 1 day later, on Wednesday.
