The Probabilities unit includes 36 most common probability distributions. All distributions support Probability Density Function (PDF), Cumulative Distribution Function (CDF) and Point Percent Function (InvCDF aka PPF):

### Discrete distributions:

• Bernoulli distribution (PDF, CDF and PPF),
• binomial distribution (PDF, CDF and PPF),
• geometric distribution (PDF, CDF and PPF),
• hypergeometric distribution (PDF, CDF and PPF),
• logarithmic distribution (PDF, CDF and PPF),
• negative binomial distribution (PDF, CDF and PPF),
• Poisson distribution (PDF, CDF and PPF),
• discrete uniform Distribution (PDF, CDF and PPF),
• Zipf distribution (PDF, CDF and PPF).

### Continuous distributions:
