I thought it would be higher than that.

Yep, 0.98 for each, but in series, it drops!

The reliability is actually 0.94 for three components in series.

I think I saw a similar question where the reliability dropped significantly with more components. Maybe it's closer to 0.94?

I feel like the answer might be lower than 0.98 since they are in series, but I’m confused about the actual calculation.

I remember a practice question where we had to multiply the reliabilities, but I can't recall the exact numbers.

I think the reliability of components in series is multiplied together, but I'm not entirely sure how to calculate that.

Hmm, I'm a bit unsure about this one. I'll need to carefully read through the details and think through the possible causes step-by-step. Compression can be tricky, so I'll need to make sure I understand the full context before selecting an answer.

Okay, I think I see what's going on here. Let me re-read the requirements and then take a closer look at the diagram.

I'm pretty sure the answer is B. The alt attribute is required for accessibility and to validate the HTML5 page.

I remember we discussed OOAD being closely related to service-orientation; it feels like a possible influence.

I wonder if the exam question has a reliability of 0.98 as well. Gotta watch out for those hidden puns!

Hmm, let me think... If the reliability of each component is 0.98, the system reliability must be lower, right?

So, the answer would be B) 0.94.

The reliability of the system in this case would be 0.98 * 0.98 * 0.98 = 0.941192, which is approximately 0.94.

Yes, that's correct. The system reliability will be lower than the reliability of each individual component.

Yes, that makes sense. So the reliability of the system would be 0.98 * 0.98 * 0.98, which is 0.942.

I agree with Ronald, because the components are in series, so we multiply the reliabilities.

I'm not sure about that. Shouldn't we multiply the reliabilities of each component to get the overall reliability?

I agree with Chanel. Each component has a reliability of 0.98, so the overall reliability should also be 0.98.
