(19459006) The Definition of the Combined Two Set ] - There is enough material related to the set taught in junior high school. One of them is about a combination of two sets. Do you know what is meant as a combination of two sets? It is better if you read again the material The Basic Mathematical Formula which discusses Understanding, Theory, Concepts And Types of Mathematical Set if you already understand Well what it is called the set then you certainly will be easier in understanding the material to be discussed in this article. Before we go further into the discussion of matter, you should first observe the following example: Pak Sukirlan went to the market for Buy some kind of fruit. After shopping Pak Sukirlan then came home with two baskets. The first basket filled with fruit kelengkeng, duku, and rambutan. While the second basket is filled with guava, passion fruit, and rambutan. Arriving at home, the fruit is put into a large basket so that the big basket now contains a mixture of fruit bought by Sir Sukirlan namely kelengkeng, duku, rambutan, guava, and passion fruit. From the examples above, we can conclude that if both baskets carried by sir Sukirlan are the sets A and B. then, the composite of the set A and B are subsets whose members are members of the set A or members of the set B. or in mathematics can be written as: [(19459007) A B = A union B (A combined B) How To Determine The Combined Two Set 1.
[1945909] if A ⊂ C then A ∪ B = B
That is, when members Set A belongs to a member of set B (A is a subset of B) then the composite of both sets contains all members of set B.
2. Both The Equal Compound
if A = B then A ∪ B = A = B
[1945906]
Meaning that if member set A is exactly the same as a member of set B, then the composite of both sets contains members of set A or B.
3. The set is not mutually exclusive
For example A = 2, 3, 4, 6, 8 and B = 2, 5, 6, 9 then AUB = 2, 3, 4, 5, 6, 8, 9
The large number of members of a composite of two sets can be determined using the following formula:
[1945909]
n (A ∪ B) = n (A) + n (19459024) [1945907] Sample Problem:
X = 1, 2, 3, 4, 6, 8
Y = 2, 4, 5, 6, 9, 11
Determine:
a. Member X ∩ Y
b. Member X ∪ Y
c. n (X ∪ Y)
Answer:
a. X ∩ Y = 2, 4, 6
b. X ∪ Y = 1, 2, 3, 4, 5, 6, 8, 9, 11
c. n n (X ∪ Y) = n (X) + n (Y) - n [19459025(X∩Y)
n (X ∪ Y) = 6 + 6 - 3
n (X ∪ Y) = 9
A few explanations and examples of the question [P] the union of the Two Associations and the Way of Determining it may help you to understand more about the matter of the set. Until we meet the subject of further mathematics lessons.
