AND
That a child is 99% less likely to go missing?
Prob of Child Missing (not in program) = 1/100 = 0.01
Prob of Child in Program Missing = 2/1000000 = 1/500000 = 0.000002

Statement 1
Prob Child Missing/Prob of Child in Program Missing = 0.01 / 0.000002 = 5000

Statement 2
(Prob of Child in Program Missing/Prob Child Missing)*100 = (0.000002/0.01)*100 = 0.02%

The child within the program has only 0.02% the chance of going missing as the child not in the program, which means (100-0.02) = 99.98% less likely to go missing
