Below is the table of population counts for a
condition and its screening test. (Recall that A
means the condition is present and B means the
screening test is positive.) On parts (a)-(e) be-
low, show enough work for me to understand
how you obtained your answer; e.g. don't just

(a) What proportion of the population is free
of the condition?
(b) What proportion of the population has the
condition and would test positive?
(c) Of those who have the condition, what
proportion would test negative?
(d) What proportion of the population would
receive a correct screening test result?
(e) Of those who would receive an incor-
rect screening test result, what proportion
would receive a false negative?
