Is the Poisson probability distribution discrete or continuous?

The Poisson distribution is discrete.

It can be.


Can Poisson probability distributions be simulated?

Yes.


What is the difference between poisson distribution and poisson process?

A poisson process is a non-deterministic process where events occur continuously and independently of each other. An example of a poisson process is the radioactive decay of radionuclides. A poisson distribution is a discrete probability distribution that represents the probability of events (having a poisson process) occurring in a certain period of time.


Relationship between Exponential and Poisson Distributions?

Poisson distribution shows the probability of a given number of events occurring in a fixed interval of time. Example; if average of 5 cars are passing through in 1 minute. probability of 4 cars passing can be calculated by using Poisson distribution. Exponential distribution shows the probability of waiting times between occurrences of events. If we use the same example; probability of a car coming in next 40 seconds can be calculated by using exponential distribution. -Poisson : probability of x times occurrence -Exponential : probability of waiting times between events.


What is the only variable in the Poisson probability formula?

What is the Assumptions for a Binomial distribution and Poisson?

For the binomial, it is independent trials and a constant probability of success in each trial.For the Poisson, it is that the probability of an event occurring in an interval (time or space) being constant and independent.


What is the difference between a binomial probability and piossion Probability?

Assuming that "piossion" refers to Poisson, they are simply different probability distributions that are applicable in different situations.


Should you use the Binomial Normal or Poisson distribution if in the past few years an average of 10 businesses closed and I want to find the probability of more than 10 businesses closing next year?

If this is the only information that you have then you must use the Poisson distribution.

Is the poisson probability of three events in one hour the same as the probability of 36 events in one day?

No. There are 24 hours in a day, not 12!
