Most frequently used probability distributions in biostatistics

In this module, you have learned about two of the most frequently used probability distributions in biostatistics: the binomial and normal distributions. The binomial distribution and the normal distribution are similar in several ways. In fact, under certain conditions, the normal distribution is used to approximate the binomial. For your initial post, discuss the following three questions. Provide examples of data that follow each distribution to help illustrate your points.

What are the basic differences between the two distributions?
Under what circumstances do you think it works well to approximate the binomial using the normal, considering the differences?
Under what public health or medical circumstances would it be helpful to identify the probability of an event? Provide some real-life examples.
