The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour. What is the standard deviation associated with the number of births within a whole day (i.e. over 24 hours)?

In a town, the number of electric power failures occurs randomly with an average of one failure every 4 months. Calculate the probability that there will be no failure over the whole year. 0.000 0.05 0.735

The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour. What is the probability that there will be at least one birth within the next 2 hours? \( \frac{0.8647}{0.6321} \) 0.1353
