Question 1141848
Odds of person with disease testing positive twice: (0.92)(0.92) = 0.8464
<pr>
Odds of person without disease testing positive twice: (0.05)(0.05) = 0.0025
<pr>
Since the odds of a person having the disease is 1/75, we weigh the values as such:
<pr>
Odds of person with disease testing positive twice: (1/75)(0.8464) = 0.01129
<pr>
Odds of person without disease testing positive twice: (74/75)(0.0025) = 0.00247
<pr>
Odds of person testing positive twice actually having disease: {{{0.01129/(0.01129 + 0.00247)}}} = 0.8205
