Suppose an assembly requires five components from five different vendors. to guarantee starting the assembly on time with 90 percent confidence, what must the service level be for each of the five components? (assume the same service level for each component).

The service level for each component must be 97.91%

Explanation:

If we want a 90% confidence of starting on time, that means we need

As the probability of each component being ready is independent from the others, that means that the probability of the 5 components being ready is equal to multiply each probability:

The probability of being ready on time is equal to the service level (in fraction), and all 5 are equal so we can say:

1

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
