Union - Correct Answer - The union of two sets is a collection of all of the
elements listed in the sets
Intersection - Correct Answer - Two sets is a collection of the elements
listed in both of the sets - Example: E={0,10,100}F={−2,−1,0,1,2}The
intersection of EE and FF is {0}, as 0 is the only element that appears in
both sets.
Theoretical Probability - Correct Answer - The ratio of the number of
equally likely outcomes in an event to the total number of possible
outcomes
empirical probability - Correct Answer - A probability that is calculated by
conducting trials or experiments and recording the results
relative frequency - Correct Answer - a way to approximate a percentage
by dividing the number of times an event occurred in an experiment by the
total number of trials
random experiments - Correct Answer - an experiment with an uncertain
outcome in which all outcomes are indepentdent of one another
,sample space - Correct Answer - the set of all possible outcomes
sample size - Correct Answer - in statistics, samples size refers to the
number of individuals measured or observed in a study. In probability,
sample size refers to the number of possible outcomes in a trial or
experiment
Venn Diagram - Correct Answer - A type of chart that illustrates how
distinct sets, topics, or objects relate to one another. Uses circles to
represent events
complement - Correct Answer - the occurence of an event not happening,
the opposite. (Complementary events are those that do not have any
common outcomes, and the union is the whole universe. One outcome is
the event itself, and the other outcome is the event not happening. For
example, flipping a coin and it landing on either heads or tails — those are
the only two possible outcomes, so the two events are complementary.)
disjoint - Correct Answer - Two events that cannot occur at the same time
Addition Rule of Probability - Correct Answer - P(A or B) = P(A) + P(B) -
P(AB)
independent events - Correct Answer - The outcome of one event does
not affect the outcome of the second event
, multiplication rule for independent events - Correct Answer - If two events
are independent, then P(A and B) = P(A) x P(B).
Whole Numbers - Correct Answer - A number whose value is 0 or
greater(Negative numbers are not considered whole numbers) and can be
represented without a fractional or a decimal component
Integers - Correct Answer - ...-3, -2, -1, 0, 1, 2, 3... all the whole numbers
together with their opposites
Rational numbers - Correct Answer - Any number that can be
represented as a fraction of two integers. Equivalently, any number which
has a decimal that either terminates or repeats. (This class of numbers
includes all integers since any integer can be expressed as a fraction)
real numbers - Correct Answer - A real number is any number that can be
placed on the number line, whether that be negative or positive, fraction or
decimal. Real numbers also include decimals that do not end and cannot
be written as a fraction. An example of this is pi (sometimes written as ππ).
Pi is approximated to 3.143.14, but the decimals do not end and do not
repeat. Everything included on the number line below is considered a real
number
Set - Correct Answer - Collection of things, usually numbers
data - Correct Answer - A set of values of qualitative or quantitative
variables; pieces of data are individual pieces of information
