WebWe define the probability distribution function (PDF) of Y as f ( y) where: P ( a < Y < b) is the area under f ( y) over the interval from a to b. (see figure below) f (y) a b. Note! If Y is … A probability distribution is an idealized frequency distribution. A frequency distribution describes a specific sampleor dataset. It’s the number of times each possible value of a variable occurs in the dataset. The number of times a value occurs in a sample is determined by its probability of occurrence. … See more A discrete probability distribution is a probability distribution of a categorical or discrete variable. Discrete probability distributions only include the probabilities of values that are possible. In other words, a discrete probability … See more A continuous probability distribution is the probability distribution of a continuous variable.
