Covid-19 ward nurses worry about the number of arriving patients in their ward. In a typical hospital, the nurses cannot accept arriving patients if there are more than 10 Covid-19 cases in a given hour. It is assumed that patient's arrival follows a Poisson process, and historical data suggest that, on the average, 5 cases arrive per hour. What is the probability that more than 20 Covid-19 cases arrive during a 3-hour shift? O a. 8.1093 x 10-8 O b.0.9582 O c. NONE O d.0.0830
