What is Set?

• collection of well defined objects.

• collection of objects.

• collection of same objects

• collection of objects having same property.

the sets having no members in it is

• unit set

• empty set

• null set

• both b and c

unit set is defined as

• set having more than two member

• set having exactly two member

• set having more than one member

• set having only one member

A={ Collection of even prime number?

• null set

• unit set

• singleton set

• both b and c

Empty set can be written as

• { }

• $\phi$

• both a and b

• none of the above.

{2} is only one even prime numbers.

• yes

• no

• confused

A={1,2,3,4,5,6,} is written as

• set builder method,

• listed method

• descriptive method

 $\cup$  if A={1,2,3,4,5,6}, B={2,4,6,8,10} Then the Union of
A and B IS
A $\cup$ B=

• {1,2,3,4,5,6,7,8,9,10}
  
  

• {1,2,3,4,5,6,8,10}

• {1,2,3,4,5,6,7,8,10}

• {2,4,6}

 $\cap$  

If P={2,4,6,8} AND Q={a,b,c,d,e} then P $\cap$  Q is

• {2,4,6}

• {a,b,c}

•  $\phi$  

• {2,4,6,8,a,b,c,d,e}

the venn diagram is example of

• overlapping set

• disjoint set

• non of the above

• both a and b
