WebProbability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval. WebAug 28, 2024 · The function underlying its probability distribution is called a probability density function. In the post I also explained that exact outcomes always have a probability of 0 and only intervals can have non-zero probabilities. And, to calculate the probability of an interval, you take the integral of the probability density function over it.
