Surprised that 10% could still slip through after two checks!

I disagree, I think it's more like 10%.

Wait, so if they add a person, it only catches 80%? That seems off.

The scanner catches 90% of poor bars, that's pretty good!

I think I might have the answer, but I’m a bit confused about how to combine the detection rates. Is it really just multiplying the percentages?

If the first check catches 90%, then 10% get through. But then the second check only catches 80% of the remaining, right?

This reminds me of a similar question we did in class about quality control. I think we need to calculate the percentage of bars that pass both checks.

I remember something about calculating the percentage of errors after multiple checks, but I'm not sure how to apply it here.

Multiple steps can receive data from the input step, that much I'm sure of. But I'm not certain about the timing - whether it's as soon as it's available or after the full fetch. I'll have to think it through.

This seems like a straightforward customer service question. I'd go with B - managing customer expectations is key to building an effective relationship.

I think the ON DELETE CASCADE means that if you delete a parent, the children get deleted too, right? It's something like option A, I believe.

So only 10% of poor quality bars would get through the checking process.

That makes sense, the further check would catch 80% of the remaining 10%.

Ha! I bet the people who made this question thought they were being sneaky. But I'm on to them - it's gotta be B) 10%.

If the scanner catches 90% and the manual check catches 80% of the poor quality bars, then the remaining 10% and 20% would still get through, right? I'm going with B) 10%.
