1. The number of calls to a health care provider follows a Poisson distribution with a mean of 33 per hour. Approximate the probability that there are less than 33 calls in an hour.
2. The number of visits to the home page of a website in a day is modeled with a Poisson distribution with a mean of 203. Approximate the probability that the number of visitors in a given day is between 194 and 208.
