A certаin fаcility prоduces drill bits mаde оf steel, cоbalt, or diamond. Suppose that 60% of the drill bits are steel, 30% are cobalt, and 10% are diamond. Further, suppose that we have the following The probability that a drill bit fails, given that it's a steel drill bit, is 20% The probability that a drill bit fails, given that it's a cobalt drill bit, is 10% The probability that a drill bit fails, given that it's a diamond drill bit, is 5% What is the probability that a drill bit fails? Show your work.
