Answer:
To get the table we have to find the following probabilities
p(A), p(B), p(not A), p(not B)
A = suspect has blond hair
B = suspect is blond
p(B) = 0.4
probability of identifying correctly = AIB = 0.90
prob of wrongful identification = Â AlB' = 0.2
Probability of A = p(AIB) *p(B) + p(AIB')*p(B')
= 0.9 * 0.4 + 0.2 *(1-0.4)
= 0.48
p( not A) = 1-0.48 = 0.52
p(not b) = 1-0.40 = 0.6
the table  has been added as an attachment
2. probability of being blond = 0.9 * 0.4 / 0.48 = 0.75
3. p(A∩B) =  0 .90 * 0.4 = 0.36
