Wait, how can the error rate be higher than the total?

Accuracy = 58/102, Error Rate = 23/48 sounds right.

I practiced a similar question last week, and I think the accuracy should be around 58/102 based on the numbers in the matrix.

I'm a bit confused about the error rate. Is it just the sum of false positives and false negatives divided by the total? I hope I got that right.

I remember calculating accuracy as the sum of true positives and true negatives over the total. I think it was something like 83 out of 102?

I feel like I might mix up the error rate and accuracy. I remember it being something like 67/102 for error rate, but I’m not entirely sure.

Remote access devices, fibre-optic, multiprotocol routers - they all sound like plausible answers. I'm going to have to guess on this one. Maybe I'll just go with the first option, A.

Hmm, I'm a bit unsure about this one. I'll need to re-read the question and options carefully to make sure I understand the differences between them.
