ETS Exam-Quantitative Business
Analysis Questions All Answered
Correct 2025-2026 Set.
Probability - Answer likelihood that a particular event will happen
Probability Formula - Answer Favorable Outcomes/Total Possible Outcomes
Statistics - Answer the collection and classification of data that are in the form of numbers
Measure of set operations - Answer the process of counting the number of elements within a
set that results from performing a set operation like union or intersection on two or more sets
union - Answer count the total number of elements that are in either set A or set B, or both
intersection - Answer count the number of elements that are common to both set A and set B
complement - Answer The complement of a set A within a universal set U is the set of all
elements in U that are not in A
Conditional Probabilities - Answer The probability of one event given the known outcome of a
(possibly) related event.
joint probabilities - Answer The probability of two events both occurring; that is, the
probability of the intersection of two events.
Counting Rules - Answer efficient means by which we can calculate the exact number of
potential outcomes for an experiment
fundamental counting principle - Answer if an event can happen in N ways, and another,
independent event can happen in M ways, then both events together can happen in N x M
ways.
