  • 0:00 - 0:06
    And the answer is 0.0333 or a 1/3 and now we're going to
  • 0:06 - 0:10
    apply the entire arsenal of inference we just learned about.
  • 0:10 - 0:18
    The joint probability of cancer and positive is 0.1 * 0.9. That's the joint that's not normalized.
  • 0:18 - 0:23
    So let's normalize it and we normalize it by the sum of the joint
  • 0:23 - 0:26
    for cancer and the joint for non-cancer.
  • 0:26 - 0:33
    Joint for cancer we just computed but the joint for non-cancer assumes the opposite prior 1-0.1
  • 0:33 - 0:37
    and it applies the positive result of a non-cancer case.
  • 0:37 - 0:41
    Now because the specificity first is negative, we have to do the
  • 0:41 - 0:46
    same trick as before and multiply it with 1-0.8.
  • 0:46 - 1:00
    When you worked this out, you find this to be 0 to 0.9 divided 0 to 0.9 + 0.9 * 0.2 that is 0.18
  • 1:00 -
    So if you put these all of this together, you get exactly a third.
