What Is Discrete and Continuous Probability Distribution

A probability distribution may be either discrete or continuous. A discrete distribution means that X can assume one of a countable (usually finite) number of values, while a continuous distribution means that X can assume one of an infinite (uncountable) number of different values.

What are the discrete probability distributions?

A discrete probability distribution counts occurrences that have countable or finite outcomes. This is in contrast to a continuous distribution, where outcomes can fall anywhere on a continuum. Common examples of discrete distribution include the binomial, Poisson, and Bernoulli distributions.

Which is continuous distribution?

A continuous distribution describes the probabilities of the possible values of a continuous random variable. … Thus, only ranges of values can have a nonzero probability. The probability that a continuous random variable equals some value is always zero.
