But, there can also be random contributions from other probability distributions such as a [[uniform distribution]], [[gamma distribution]] and so on.
The probability distribution can be modeled from the the measurement data. Then, the probability distribution can be used to model an equivalent possibility distribution using the maximally specific probability-possibility transformation.<ref>{{Cite journal|last=KLIR†|first=GEORGE J.|last2=PARVIZ|first2=BEHZAD|date=1992-08-01|title=Probability-Possibility Transformations: A Comparison|url=https://doi.org/10.1080/03081079208945083|journal=International Journal of General Systems|volume=21|issue=3|pages=291–310|doi=10.1080/03081079208945083|issn=0308-1079}}</ref>
Some common probability distributions and the corresponding possibility distributions can be seen in the figures.
