A disease diagnostic test is 90% accurate on those who have the disease
(that is, sensitivity equals 0.90) and 80% accurate on those who do not have
the disease (that is, specificity equals 0.80). Assume that 0.05 of the tested
persons have this disease.
What is the probability that a tested person has the disease and a negative
result? (Hint: This is a probability of an intersection).
