Probability distribution
A description of the possible values of a random variable and of the probability of occurrence of these values.
8 of 13
Discrete probability distribution
When the random variable can only take a finite set of possible values.
9 of 13
Binomial Distribution
Describes the probability of a characteristic that can only take two values.
10 of 13
Continuous probability distribution
When the random variable is continuous, taking an infinite set of values within a range.

Random Variable
A variable which can take different values with given probabilities.
