A factory is making cat plushies. Each plushie that gets made can either be of good quality or can be defective. If a cat plushie is of good quality, then the next plushie that gets made is also of good quality with probability . If instead a cat plushie is defective, then the next plushie that gets made is also defective with probability . If you see that the factory just produced a defective plushie, what is the expected number of plushies that are made before the next defective plushie?
