Suppose you have a test which is said to be 99% effective at detecting terrorists, and that this is used in mass surveillance on a population of a million people. Suppose the measure of 99% effective applies both to the detecting people who are terrorists and detecting that people are innocent which means that the false match rate and the false non-match rate are both 1%.

Suppose furthermore that among the million people there are 100 terrorists.

1. How many genuine terrorists will be found?

2. How many terrorists will escape detection (false non-matches)?
