A nice simple visualization of this classic probability problem.

https://x.com/howie_hua/status/2048452433895129532

This is a very common misconception in statistics:

If 1% of a population has a disease and the tests have a 5% chance of giving a false positive, what's the probability of having the disease given that we tested positive?

The answer is NOT 95%. It's actually way less. pic.twitter.com/HoLm7zOTjB
