Amachine needs 2 of its gears replaced. you find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago. the specifications sheet says that the chance of failure is 5% after 5 years and increases to 8% after 10 years. if the gears on the machine are in no way linked to each other, what are the chances that both will fail? answer in % form.
if someone could show me the steps i would really appreciate it! !
