The disease progression in sepsis (a systemic inflammatory response syndrome (SIRS) together with a documented infection) is recently modeled mathematically. Both sepsis, severe sepsis and septic shock may be life-threatening. The researchers estimate the probability of sepsis to worsen to severe sepsis or septic shock after three days to be 0.2. Suppose that you are physician in an intensive care unit of a major hospital, and you diagnose four patients with sepsis. What is the probability that at most one patient with sepsis get worse in the next three days? Provide your answer in decimal format with 3 decimal points
