Thank you. The question throws out "prevalence of 1/1000" but then asks about only people with a positive result... a result that is wrong 5% of the time. It doesn't ask about the odds of some random dude having the disease, which is what people are trying to answer. It only asks about people who already have tested positive. And if the test gives a false positive 5% of the time, then 5% of the people who tested positive got the wrong result. People who tested negative aren't part of the actual question. It's more about reading comprehension than maths skills.
If thats an accurate take, then there is a subset of people who are lacking in one life skill, who believe they are more intelligent than the majority because they don't get the same answer..
Now I think I've got to re-examine/reaffirm my beliefs on covid, the 6 million, and lord knows what else..
