The most basic difference between probability mass function and probability density function is that probability mass function concentrates on a certain point for example, if we have to find a probability of getting a number 2. Then our whole concentration is on 2. Hence we use pmf however in pdf our concentration our on the interval it is lying. For e.g.$ -\infty <= X <= \infty $. Always

**Poisson approximation to the binomial The Poisson Distribution**

For discrete distributions, the probability that X has values in an interval (a, b) is exactly the sum of the PDF (also called the probability mass function) of the possible discrete values of X in (a, b). stretching exercises for lower back pain pdf Probability Mass Function The Poisson distribution is used to model the number of events occurring within a given time interval. The formula for the Poisson probability mass function is

- Solution: a. Recall, a function is a probability density function if the area under the curve is equal to 1 and all of the values of p(x) are non-negative.
- To have a better insight let us practice some conditional probability examples, Example: Two die are thrown simultaneously and the sum of the numbers obtained is found to be 7 . What is the probability that the number 3 has appeared at least once? Solution: The sample space S would consist of all the numbers possible by the combination of two dies. Therefore S consists of 6 ? 6 i.e. 36 events
