Sensitivity is calculated as True Positives / (True Positives + False Negatives).

I think the answer might be A or B, but I can't recall the exact values from the matrix. I hope I can work it out quickly during the exam!

I feel like I might confuse the true positives with false positives. I need to double-check which values to use for the calculation.

I remember practicing a similar question where we had to find sensitivity, and I think it was about identifying the right counts from the confusion matrix. I hope I can remember the formula correctly!

I think sensitivity is calculated as true positives divided by the sum of true positives and false negatives, but I'm not completely sure about the numbers to use from the matrix.

Okay, I think I've got it. The camera is sensitive to IR light in low-light mode, and the most common near-IR wavelength used in imaging is around 850 nm. That's my best guess.

If I recall correctly, FF0000 is definitely red. The other options don't seem right based on what we studied.

I'm a bit unsure about this one. I know the services are managed through the Control Panel, but I'm not sure which specific location. I'll have to think it through carefully.
