A distribution that deals with all the possible values and likelihoods that a random variable can take within a given range.

• Probability Distribution

• Statistics and probability

• Probability dispersion

It is the central or average of its corresponding probability mass function.

• mean

• median

• mode

• standard deviation

This determines the probability of a random variable X falling into an interval

• Area of Probability

• Area of possibility

• Area of Likeliness

The standard deviation of the sampling distribution of the sample mean is the square root of its variance
