Q2. Describe the solution of time to failure in hours of an important piece of electronic equipment used in manufactured DVD player has density function.
H=7

F(x)= 1/1000(H+1)*exp (-x/1000(H+1) X > 0
0 , X < 0

(A) find F(x)
(B) Determine the probability that the component (and thus DVD player)lasts more than 1000 hours before the component needs to be replaced
(C) Determine the probability that the component fails before 2000 hours.
