The Trouble With Numbers and Math

 Just a comical but factual thing to lay out.

Cambridge University decided that every single kid in the place (9,000-plus students) needed to be Covid-tested. 

Results?  ALL 9,000-plus students were identified with a positive (probably scared the crap out of their parents as the word came out).

We aren't talking 25-percent, or 50-percent.  This was 100-percent (in the end) with a 'positive' given on the test result.  

A second test was administered at this point.....it's best not to ask why they didn't accept the first test results.  In the second test?  NOT one single person was found to be positive.

The odds that both the 1st test and 2nd test are inaccurate?  Well....that's the thing you'd ponder about.

Logically, even on the second test, you should have had 1-percent show up with a true-positive.  

Will they do the test a third time?  The hint is no.  But I'm estimating the math professors are sitting there and grinning.....you can't have two tests, where one is absolutely 100-percent positive, and another being absolutely 100-percent negative.

Just something to think about.
