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.
