The mean number of daily surgeries at a local hospital is 6.2. assume that surgeries are random, independent events. (a) the count of daily surgeries follows approximately: a poisson distribution with mean 6.2 and standard deviation 2.49. a binomial distribution with mean 6.2 and standard deviation 3.8. a binomial distribution with mean 6.2 and standard deviation 1.76. a poisson distribution with mean 6.2 and standard deviation 6.2. a binomial distribution with mean 6.2 and standard deviation 3.1. (b) the probability that there would be only 2 or fewer surgeries in a given day is approximately (round to 4 decimal places):
