Homework Statement
I've attached both the problems into one image to make life easier since problem 1 has a diagram and the other does not.
Homework Equations
Bayes Theorem : P(A|B)P(B) / [P(A|B)P(B) + P(A|B')P(B')]
B' = B Complement
The Attempt at a Solution
well for the first one
i don't understand what the P(A|B') is and the .849 is that referring to B'?
SO i did .001(.05) / [(.001(.05)) + P(A|B')(.849)] i don't know what that P(A|B') is so I am not sure where to go from there and the answer in the back of the book says .0099
for the 2nd problem
a.) i understand don't need help
b.) i don't know how to get P(AB) given the information provided
c.) well i can get this if i know part b since it would be .4 + .25 - P(AB)
thank u for ur help!
