Question

The amount of time, in hours, that a computer functions before breaking down is a continuous random variable with probability density function given by

$f(x)=\left\{\begin{array}{ll}{\lambda e^{-x / 100}} & {x \geq 0} \\ {0} & {x<0}\end{array}\right.$

What is the probability that a computer will function between 50 and 150 hours before breaking down? What is the probability that it will function less than 100 hours?
