The Sleeping Beauty Problem: What's the Probability?

TLDRThe Sleeping Beauty problem is a controversial puzzle in probability theory. The question is: what is the probability that the coin came up heads? One perspective says it's 1/2, while another says it's 1/3. There is no consensus solution, but it has implications for our philosophy of probability and anthropic reasoning.
