Question

Suppose the lifetime of a certain bulb follows a uniform distribution between 1000 hours and 1200 hours. What is the probability that a randomly selected lightbulb will last between 1100 hours and 1150 hours, given that the bulb nas been working for at S-least 1100 hours? Also, find the mean and variance of the lifetime of the bulb.
