pose that a light fixture has 100 light bulbs installed. The lifetimes of light bulbs are independent exponential random variables with a common mean equal to 800 hours. Because replacing a light bulb involves someone climbing up the fixture, the owner decides not to replace bulbs until 5 light bulbs have burned out. If currently all the 100 light bulbs are working, find the expected time until the needs to replace the bulbs.
