An experiment that yields a random sequence of outcomes when it is repeated.
Probability
For a possible outcome θ from random experiment Y, the probability of θ is the fraction of times that θ occurs when Y is repeated an infinite number of times.
Discrete quantitative variable
If it has a finite number of possible values within any finite portion of the real number line.
Discrete probability distribution
Is a list of all possible values and their probabilities for a discrete random variable
Continuous variable
If within a defined domain of the real number line, every real number is a possible value.
Cumulative probability
For a quantitative random variable X and a real number θ, the cumulative probability of θ, written as F(θ), equals the probability that X≤θ
