- Module 7 Question and answer
correctly solved 2025
dependent events - correct answer ✔Two events for which the occurrence of
the first affects the probability of the second.
experiment - correct answer ✔A procedure that can be done repeatedly
which has a well defined set of outcomes.
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.
population - correct answer ✔An entire pool from which a sample is drawn.
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.
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.
probability - correct answer ✔The chance of an event occurring.
random experiment - correct answer ✔Experiment in which the outcome is
not known ahead of time and in which results do not | affect future outcomes.
, EX - flip a coin ten times, and each will be a random experiment.
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.
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.
Number of Outcomes Corresponding to the Desired Event
Total Number of Outcomes that can occur
EX
P(Bob wearing a blue suit) =
3 blue suits
5 suits total =
3/5 or 0.6 or 60%
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.
event - correct answer ✔An outcome, or set of outcomes, whose chance of
occurrence can be represented with a probability.
EX: rolling a die, the die landing on an even number is an event. The die
landing on 11 is also an event.
