Module 7 Exam Review Focused on
Probability Questions and Answers 2024/2025
Disjoint - correct answer two events which cannot both occur
at the same time.
Intersection - correct answer the intersection of a and b will
have all elements that are in both a and b. You can think of an
intersection as 'a and b,' since it contains an element if it is in a
and in b. The intersection of many sets will have an element if it
appears in all of the sets..
Random experiment - correct answer experiment in which
the outcome is not known ahead of time and in which results do
not affect future outcomes.
Sample - correct answer the small quantity of data gathered
about a population that will represent the population as a whole.
Population - correct answer an entire pool from which a
sample is drawn.
Dependent events - correct answer two events for which the
occurrence of the first affects the probability of the second.
,Relative frequency - correct answer a way to approximate a
probability by taking the number of times an event occurs
divided by the total number of trials.
Union - correct answer the union of a and b will have all
elements in a, all elements in b, and all elements in both. You can
think of a union as 'a or b,' since it contains an element if it is in
a or in b. The union of many sets will have an element if it
appears in at least one set.
Empirical probability - correct answer an estimation of
probability derived from recording data about what has
happened during a series of experiments.
Complement - correct answer an event that is the opposite of
another event. The complement of heads when flipping coins is
tails. The probabilities of an event and its complement always
sum to 1.
Independent events - correct answer events, where the
occurrence of one does not affect the probability that the other
event(s) will occur.
Event - correct answer an outcome, or set of outcomes,
whose chance of occurrence can be represented with a
probability.
Probability - correct answer the chance of an event
occurring.
, Fair - correct answer an experiment in which all outcomes
are equally likely.
Sample size - correct answer the number of different
outcomes for an experiment.
Tree diagram - correct answer a diagram that records all the
events in a sample space by attaching each new set of events to
each branch of the earlier events. The number of outermost
branches gives the sample size.
Sample space - correct answer the entire set of outcomes for
a trial or experiment.
Theoretical probability - correct answer also called the
actual, exact, or classical probability, it is computed by dividing
the number of outcomes where the desired event occurs by the
total number of outcomes. Note that the outcomes must be
equally likely.
Frequency table - correct answer a table which records the
frequency of instances in different categories. It can be used to
determine if the categories are dependent or independent.
Law of total probability - correct answer a fundamental
principle of probability which states that the product of all
branches of a probability tree, added together equals 1.
