A washing machine is warranted to last for 2,500 hours. If the time to failure is exponentially distributed with a true mean of 1,900 hours, what is the probability that it will last at least 2,500 hours?

A component has an exponential time to failure distribution with a mean of 10000 hours. (i) The component has already been in operation for its mean life. What is the probability that it will fail by 15000 hours? (ii) At 15000 hours the component is still in operation life. What is the probability that it operates for another 5000 hours?
