When working out problems that have a uniform distribution, be careful to note if the data is inclusive or exclusive.

Webb28 aug. 2024 · In my previous post I introduced you to probability distributions. In short, a probability distribution is simply taking the whole probability mass of a random variable and distributing it across its possible outcomes. Since every random variable has a total probability mass equal to 1, this just means splitting the number 1 into parts and […] Webb23 feb. 2024 · A probability distribution table is a table that displays the probability that a random variable takes on certain values.

Webb14 jan. 2024 · In this post, you will learn the definition of 25 different types of probability distributions. Probability distributions play an important role in statistics and in many other fields, such as economics, engineering, and finance. They are used to model all sorts of real-world phenomena, from the weather to stock market prices. WebbThe averages are the same but the distribution of results isn’t the same. On a d30 all the results have an equal probability, while a d20+2d6-2 would give an average of 15.5, but the probability of getting a 1 or 30 is a 1 in 720 chance, instead of a 1 in 30 chance.

IMO, when a paper or a book says these "data are drawn from a probability distribution P", it means "we generated this data so it conforms to our theoretical notions about P".
