Math 2021/2022 (Statistics and Probability)
Addition Correct Answer: For mutually exclusive events we can use the ____ Principle of Counting.
Addition Rule Correct Answer: For probability this rule states that (A ∪ B) = P(A) + P(B) - P(A ∩ B)
Average Correct Answer: This is the sum the numbers in a set, divided by the number of items in the
set.
Average Correct Answer: You get this when you add a group of numbers and then divide by how many
numbers you have.
Bar Graph Correct Answer: This is a graphical means of quantitative comparison by rectangles with
lengths proportional to the measure of the data or things compared.
Categorical Data Correct Answer: Data that cannot be measured, but is divided into groups.
Central Correct Answer: The mean, median, and mode of a set of data are called measures of _____
tendency.
Certain Correct Answer: An event is called _____ if the probability it will occur equals 1.
Circle/Pie Graph Correct Answer: This is a circular chart cut by radii into segments illustrating relative
magnitudes or frequencies. These are great for displaying percentage data.
Combination Correct Answer: Counts the number of ways objects can be formed into groups of a
certain size.
Combinations Correct Answer: This is a way to count the number of outcomes: one or more elements
selected from a set without regard to the order of selection. The formula is written as follows: Cn,r =
(n!)/[r!(n-r)!]
Complement Correct Answer: The set of all elements that are in the universal set but not in the set you
are talking about.
Complementary Correct Answer: If two events have probabilities which sum to 1, they are called
________ events.
Conditional Probability Correct Answer: The probability that event B will occur, given that event A has
occurred, is called its ____ probability.
Counting Correct Answer: A way of computing the possible number of outcomes in an experiment. It is
called the ___ Principle.
Data Correct Answer: When gathering information for research we say we are collecting _____.
