SETS
► Sets: "a collection of welldefined distinct objects".
Descriptive form: One way to specify a set is to give a verbal description of its
elements.
Examples: (Set of first ten odd integers.) (Set of vowels of English alphabets.)
Tabular form: Members of a set are written within braces and are separated by
commas.
Examples: A = {1,3,5,7,9, 11, 13, 15, 17, 19). B={a, c, i, o, u}
Set Builder form: Setbuilder notation is a mathematical notation for describing a
set by enumerating its elements or starting the properties that its members must
satisfy.
Example: A= {xx is odd number and is less than 20)
B = (xxis vowel of English alphabets)
{3, 4, 5, 6,...) = {X ENIX > 2) its read as "the set of all x's in natural number,
such that x is greater than 2".
> Union of two or more sets: If A and B are any two sets, then the union of set A and
Set B consists of all elements in set A or in set B and is denoted by AUB.
Example: If A= {1,2,3), B=(3,4,5) find AUB.
AUB= {1, 2, 3, 4, 5)
325
The intersection of two or more sets: If A and B are any two sets, then the intersection
of set A and set B consists of all those elements which are common to both A and B.
and it is denoted by ANB.
Example: If A=(1, 2, 3. 4), B.(3,4,5} find ANB.
ANB (3, 4)
J
> Difference of two sets: If A and B are two sets then their difference consists of all
those elements of set A which are not in set B and it is denoted by ABor A/B.
Example: IfA= {2,3,4,5,6), B=(5, 6, 7, 8) find ABor A/B =?
AB or A/B= {2,3,4,5,6)  {5, 6, 7, 8)= 12,3,4}

Disjoint set: Two sets A and B are disjoint sets if they do not have any common
clementine. ANB==
Example: A = {4, 5) and B = (6, 7, 8), find ANB=?
ANB = {4,5} n {6, 7, 8) = {}

Q: What is Median?
Median: The median is the middle value of (ascending or descending) data, il
the number of values is odd. Then the middle value will be the median.
Solution: Ascending order 1.4.4,5,5.7.7.7.8
MATHEMATICS CLASS8
value is even, then the mean of two Michelle values will be the mean of the data.
Example No 1: Calculate the median of the data given below
65.55, 89, 56, 35, 14, 56, 55, 87,45.92
Solution: First arrange this data in ascending order 14, 35, 45, 55, 555, 56, 65, 87, 89, 92
(5(1)
= 6 So the sixth number (56) is median.
Example No 2: Calculate the median for the data given below:
63, 55, 89, 56, 35, 14, 56, 55, 87,45
Solution: First arrange this data in ascending order 14, 35, 45, 55, 55, 56, 56, 65, 87, 89

Median
= 55.5

Q: What is the mode?
Mode The mode is the most frequently occurring values in data,
Example: The following are the Maths marks of the Aftab in the month of
December 2013. Find the mode of the marks 45, 41, 85, 90, 41, 66, 95, 41
Solution: First arrange this data in ascending order 41, 41, 41, 45, 66, 85,95
So the most frequent value is 41, so the mode of the number is 41.
MCQs
