What are the two main type of defined sets??

• Well defined set

• Un-defined set

Answer explanation

A well-defined set is a set which we can easily explain or understand.

An un-defined set is a set which we can not easily explain or understand.

In the given example the elements are

(a)  

Which of the following statements are true for the Venn diagram shown?

• Overlapping sets

• Subsets

• Disjoint sets

• Equal sets

Which symbol is not given in the image?

• =

• n(A)

• U

• A U B

A = {x : x is a letter in the word SEAT}

B = {x : x is a letter in the word TASTE}

Determine if these two sets are equal or equivalent.

• Not equal because seat has 4 letters and taste has 5 letters.

• Equivalent because they have the same letters

• Equal because each set has the same cardinality and the same letters.

From the above Venn diagram, what is the set (S ∪  T) ∩ V?

• {casey, drew, jade, glen}
• {alex, glen, hunter, jade}
• {casey, drew, glen}
• {drew, jade}

What is the union of sets A and B?

• {x : x is a letter in the word SEAT}

• {x : x is a letter in the word TASTE}

• {x : x is a letter in the word SEAT or TASTE}

Which symbol is missing in the image?

• =

• n(A)

• U

• A U B

What is the intersection of sets (S ∪ T) and V?

• {casey, drew, jade, glen}

• {alex, glen, hunter, jade}

• {casey, drew, glen}

• {drew, jade}

Which of the following statements are true for the Venn diagram shown?

• Overlapping sets

• Subsets

• Disjoint sets

• Equal sets
