Chapter 7, Problem 70E(choose chapter or problem)
Electronic chips Suppose the probability that a particular computer chip fails after t = a hours of operation is \(0.00005 \int_{a}^{\infty} e^{-0.00005 t} \ d t\).
a. Find the probability that the computer chip fails after 15,000 hr of operation.
b. Of the chips that are still operating after 15,000 hr. what fraction of these will operate for at least another 15,000 hr?
c. Evaluate \(0.00005 \int_{a}^{\infty} e^{-0.00005 t} \ d t\) and interpret its meaning.
