A witness identified a suspect as having blond hair. However, when tested under lighting conditions similar to those on the night of the incident, it was concluded that the probability of correctly identifying blond hair was 0.90 and the probability of being incorrect about non-blond hair was 0.2. Suppose that 0.4 is the proportion of persons with blond hair that live in the area. Let two events A and B be defined as A = [ Identified as blond and B = [ Person is blond] 1. Fill in the four probabilities, and the marginal totals, in the two-way table. using... (A, B, Not A, Not B) 2. Given that this person was identified as blond, find the probability of being blond 3.
