APPLIED PROBABILITY AND
STATISTICS - C955 QUESTIONS &
ANSWERS
Basic probability - ANSWER#of total come\# of total outcome in the sample space
P(B | A) - ANSWERconditional probability
P(A and B)=P(A) • P(B) - ANSWERmultiplication rule- independent events
P(A and B)= P(A) • P(B|A) - ANSWERmultiplication rule- dependent events
P(A or B)= P(A) + P(B) - ANSWERaddition rule- Disjoint
P(A or B)= P(A) + P(B) - P(A and B) - ANSWERaddition rule- non-Disjoint
product - ANSWERThe result of multiplying values.
factorization - ANSWERThe process of determining the prime factors of a composite
number.
integer - ANSWER"A number, (positive, negative, or zero), that can be represented
without a fractional or a decimal component."
superscript - ANSWERA symbol (such as a number or letter) written above and
immediately to the left or right of another character.
perfect square - ANSWER"The product of any integer with itself. . So, a number is a this
if it can be written as the square of an integer. For example, 3 * 3 = 9."
expression - ANSWER"A string of terms that are connected by division, addition, and
subtraction operations."
addition - ANSWERFinding the total of two or more values.
interval - ANSWERA set of numbers between two specified values.
difference - ANSWERThe result of one number being subtracted from another number.
multi-step expression - ANSWERAn expression or equation with more than two values
and two or more operators that requires multiple steps to be solved.
,discrete - ANSWER"A collection of numbers whose values are distinct, separate, and
unconnected."
negative number - ANSWER"A number whose value is less than zero. On the number
line, they are to the left of zero."
division - ANSWERSplitting values into equal parts or groups.
estimation - ANSWERApproximating a value for a calculation
radical sign - ANSWERThe symbol which indicates to take the square root of the
number that follows.
numbers - ANSWERA word or symbol (such as 'five' or '16') that represents a specific
amount or quantity.
exponents - ANSWER"Sometimes called a power, it is a quantity that represents
repeated multiplication."
parentheses - ANSWER"In mathematics, these () are used to separate operations
within an expression. Any operations that lie within parentheses should be performed
first."
real number - ANSWER"Any numbers on the number line. They include zero, negative
and positive integers, fractions, and decimals."
sum - ANSWERThe result of multiple numbers being added together.
square root - ANSWERA number that produces a specified number when it is multiplied
by itself.
Fundamental Theorem of Arithmetic - ANSWERA concept which states that any integer
greater than 1 is either prime or is the product of a unique set of prime numbers.
prime number - ANSWERA number with only two factors: one and itself.
operator - ANSWERA word or symbol (such as + or -) that indicates an operation
between values.
principal square root - ANSWER"The positive square root of a number. For example,
the principal square root of 36 is 6."
whole number - ANSWERA number whose value is 0 or greater (negative numbers are
not considered this), and can be represented without a fractional or a decimal
component.
, positive number - ANSWER"A number whose value is greater than zero. On the number
line, these numbers are to the right of zero."
additive inverse - ANSWER"Two numbers equidistant from 0 on a number line whose
sum is 0. For example, 3 and -3
commutative - ANSWERThe property that the order of the numbers under the operation
does not change the result. Addition and multiplication are this: a + b = b + a and ab =
ba.
multiplicative inverse - ANSWER"opposite of a number x is the number you must
multiply x by to get 1. For example, 5 and 1/5 are this."
negative square root - ANSWER"The negative compliment of a perfect square. For
example, -6 is the this of 36."
operation - ANSWER"In mathematics, this is a procedure which generates a new value
from one or more operands, or mathematical values."
identity property - ANSWER"The property that 0 can be added to any number without
changing the value of the number. Likewise, 1 can be multiplied by any number without
changing the value of that number."
rational number - ANSWER"This type of number is a number that can be written as a
ratio of integers, which means it can be written as a fraction."
order of operations - ANSWERA set of rules that defines the order in which
mathematical operations should be performed
associative property - ANSWER"This property holds that under certain operations in a
multi-step expression, the computations may be done in any order. Commonly
represented as (a + b) + c = a + (b + c). Addition and multiplication follow this property"
prime factorization - ANSWERDetermining the set of prime numbers whose product is
the original integer.
continuous - ANSWERA collection of numbers whose values are not dividable into
distinct units.
composite number - ANSWERA number with more factors than just one and itself.
multiplication - ANSWER"In mathematics, this is the act of adding the same number
multiple times. It is often denoted by the dot sign, ·."
base number - ANSWER"The number multiplied by itself when paired with an exponent.
For example, in 8 to the third power, 8 would be this number."
