Prisoners

It is estimated that 10% of all federal prisoners have a positive self-image, 40% have a neutral self-image, and the rest have a negative self-image. The estimated probability of rehabilitating a prisoner with a negative self-image is 0.1. With a neutral self-image, this estimated probability is 0.4, and with a positive one, it is 0.8.

A prisoner is rehabilitated. What is the probability that the original self-image was negative?
A) 0.17 C) 0.63
B) 0.71 D) 0.36

A prisoner is not rehabilitated. What is the probability that the original self-image was negative?
A) 0.36 C) 0.63
B) 0.71 D) 0.17

p1 =  0.1724
p2 =  0.6338
