The time to failure in hours of an important piece

The time to failure in hours of an important piece of electronic equipment used in a manufactured DVD player has the density function
(a) Find F(x).
(b) Determine the probability that the component (and thus the DVD player) lasts more than 1000 hours before the component needs to be replaced.
(c) Determine the probability that the component fails before 2000hours.
