The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.4. What is the appropriate probability distribution for the random variable? a)continuous b)either discrete or continuous depending on how the interval is defined c)binomial d)discrete

An article suggests that a Poisson process can be used to represent the occurrence of structural loads over time. Suppose the mean time between occurrences of loads is 0.5 year. For every single part, clearly define the random variable of interest using the context of this problem. (Hint: We are given that the mean time between occurrences of loads is 0.5 year. It is not the λ value to be used in Poisson process since it is the mean time...

The Binomial and Poisson Distributions Both the Binomial and Poisson Distributions deal with discrete data where we are counting the number of occurrences of an event. However, they are very different distributions. This problem will help you be able to recognize a random variable that belongs to the Binomial Distribution, the Poisson Distribution or neither. Characteristics of a Binomial Distribution Characteristics of a Poisson Distribution The Binomial random variable is the count of the number of success in n trials: number of...

7, If the number of event occurrences is Poisson distributed, successive occurrences is exponentially distributed. In certain locations in Texas, sudden heavy rainfall may produce sudden floods, called flash floods, because of the land surface geometry and other geographical factors.
