Hey /sci/, I have a quick question that will probably get me laughed at, but I'd prefer a genuine answer because I'm not to keen on math, seeing as I stopped taking it in 9th grade.

So say there's a 25% chance of an event happening, but a safeguard with a 70% success rate is in place. On top of that, there is another safeguard with an 89% success rate active. What would be the chance of the event occurring?

I know you guys probably don't like answering questions like these but I'd too curious to not know.

So, 25% chance times chance of safeguard A failing AND X chance of safeguard B failing

so 0.25 X 0.3 X 0.11
=0.00825
or 0.825%

25% + 70% + 89% / 3
=
33.34%

more or less a game of luck

Does the safeguard make the event happen or not happen? Be clear about exactly what you want to know.

OP, are you thinking about using contraception?
