CPP-FMC-5 [Sets]

Definition of set :

• Set is not a well defined collection of objects.

• Set is a well defined collection of objects.

• Set is a well defined collection of numbers.

• Set is a well defined collection of problems.

Definition of Universal Set:

• In any particular context, a set from which all the subsets are formed is called universal set.

• Universal set is large set.

• Universal set is smallest set

• Universal set is complement of a set.

If A and B are two subsets of universal set , Then union of A and B is denoted as

•  $AUB$  

•  $A\cap B$  

•  $A\cup B$  

•  $A-B$  

Difference between Set B from Set A is

• $A-B$

• $B-A$

• $\overline{B}-\overline{A}$

• $\overline{A}-\overline{B}$

........are the four basic operations of set ?

• Union, Intersection, Complement and Difference.

• Difference, Intersection, Complement and Universal.

• Universal, Subset, Null Set and Union Set.

• None of above.

Shaded portion shows ...

• Union of set P and set Q

• Intersection of set P and set Q

• Complement of set P

• Difference of set P from set Q

Dark shaded portion is

• Union of set P and Q

• Intersection of set P and Q

• P-Q

• Q-P

Shaded Portion shows ...

• A-B

• B-A

• A

• $\overline{A}$

If $V=\left\{a,e,i,o,u\right\}$  How many subsets can be made from this set?

• 22

• 12

• 26

• 32

The cardinal number of set P={ 3,4,5........20} is

• 4

• 18

• 17

• Non of above
