Although COVID infection rates have been declining in the US lately, it is possible that a new variant of the virus could appear in the coming months and cause a 10% or larger correction in the US stock markets during 2022. Suppose you read an interview in Barron's that cites comments provided by an experienced market analyst, and she argues that the probability of the 10% or larger correction in the S&P 500 during 2022 is 0.20 (i.e., 20%). Is the probability value cited in the article an empirical probability, a subjective probability, or an a priori probability?
