is known, probabilities can be deduced from theoretical arguments.
Relative Frequency Definition - ANSWER-Based on empirical data. The probability that
an outcome will occur is simply the relative frequency associated with that outcome.

Continuous random variable - ANSWER-Outcomes of one or more continuous variables
of real numbers.
Properties of probability density functions - ANSWER-must lie at or above x-axis
total area above the x-axis is 1
for continuous random variable there are infinite values
P is the are under the density function
