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

Ah, the good old series reliability calculation. This should be a piece of cake!

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.
