2.10. Alice and Bob are at the gym. They will first ride stationary bikes for an exponentialy distributed amount of time with means 30 and 20 minutes. Then they will lift weights for an exponentially distributed amount of time with means 10 and 15. (a) What is the probability Alice finishes first? (b) How long does it take until they are both done?
