Ha! I bet the answer is D. 0.26. Just kidding, I know it's A. Gotta keep a sense of humor, right? Now, where's the coffee...

Alright, time to put on my thinking cap. Okay, got it! The formula is R = e^(-t/MTBF), and with the given values, it comes out to 0.87. Nice and simple, just the way I like it.

Wait, what? How did you guys get 0.87? I calculated it as 0.78. *scratches head* Maybe I'm missing something here...

Alright, let's see... R = e^(-t/MTBF), so plugging in the values, we get R = e^(-800/600) = 0.87. Looks like A is the correct answer!

I'm not sure, but I think the formula involves MTBF and failure rate.
