Question

If the mean time between unscheduled maintenance of LCD displays in a hospital’s CT scan facility is 4000 hours, what is the probability of unscheduled maintenance in the next 6000 hours

Answer 1

Likely

6000 hours is over the mean average, but it is not impossible that it will not happen.

Answer 2

Answer: the probability is 0,7135

Step-by-step explanation:

This is an Exponential Distribution

1/λ = 4000

We apply the formula and we will get this: 1 - $e^{\frac{-1}{4000} . 5000 }$ = 0,71345
