Johnny carries out an experiment to study the lifespan of cockroach without water and food. At the end of day 0, he puts six cockroaches in different boxes respectively. On each day following, each cockroach has an equal chance to die with a probability of 0.5. What is the expected number of days until all six cockroaches die?
