A Poisson distribution is appropriate when you have events that occur
- independently of one another in space or time,
- at a constant rate, and
- occur singly.
The last condition means that the probability of more than one event occurring at any particular point in space or time is zero (or negligible).
However, if the parameter (mean) of the Poisson distribution, L, is greater than 10, you may be better off using the Normal approximation, N(L, L), with the appropriate continuity corrections.

If X has Poisson distribution does aX plus b have Poisson Distribution?
Yes.
Why belong exponential family for poisson distribution or geometric distribution?
Why belong exponential family for poisson distribution
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.
Which distribution function has equal mean and variance?
The exponential distribution and the Poisson distribution.
Given a Poisson distribution with mean equals 2 Find P x5?
Given a Poisson distribution with mean = 2. Find P(X < 5)
Which distribution is used to find probabilities about the number of independent events occurring in a fixed time period with a known average rate?
The Poisson distribution. The Poisson distribution. The Poisson distribution. The Poisson distribution.
Is the Poisson probability distribution discrete or continuous?
The Poisson distribution is discrete.
If X has Poisson distribution does aX plus b have Poisson Distribution?
Yes.

What is the difference between poisson and binomial distribution?
Poisson and Binomial both the distribution are used for defining discrete events.You can tell that Poisson distribution is a subset of Binomial distribution. Binomial is the most preliminary distribution to encounter probability and statistical problems. On the other hand when any event occurs with a fixed time interval and having a fixed average rate then it is Poisson distribution.
Whose distribution belong exponential family?
Poisson distribution or geometric distribution
Which distribution function has equal mean and variance?
The exponential distribution and the Poisson distribution.
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.
Which shape describes a Poisson distribution?
symmetrical
Is the sample size in poisson probability distribution?
It can be.
What are the properties of poisson distribution?
It is a discrete distribution in which the men and variance have the same value.
