Test: Operations On Sets - Question 1

### Which of the following two sets are disjoint?

Detailed Solution for Test: Operations On Sets - Question 1

{1,3,5}&{2,4,6} are disjoint sets.

Explanation:

In {1,3,5} & {1,3,6} 1 and 3 is the same numbers.

In {1,2,3} & {1,2,3} 1,2 and 3 is the same numbers.

In {1,3,5} & {2,3,4} 3 is the same number.

In {1,3,5} & {2,4,6} not any numbers are same.

Test: Operations On Sets - Question 2

### The Shaded region in the following figure illustrates Detailed Solution for Test: Operations On Sets - Question 2

First which region is over which region Then We will see that A is on the B so A intersection B and after C is on the A so, A intersection C after that we have to take all intersection part so A intersection B is Union with A intersection C.

The shaded region represents (A ∩ B) ∪ (A ∩ C).

Test: Operations On Sets - Question 3

### Shaded region in the following figure illustrates Detailed Solution for Test: Operations On Sets - Question 3

P U Q means P Union Q In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other.

Test: Operations On Sets - Question 4

If the sets A and B are defined as= {(xy) : ex∈ R}; = {(xy) : x,∈ R}, then

Detailed Solution for Test: Operations On Sets - Question 4

Since,ex andx do not meet for any∈ R∩ φ.

Test: Operations On Sets - Question 5

The intersection of the sets {1, 2, 5} and {1, 2, 6} is the set ______

Detailed Solution for Test: Operations On Sets - Question 5

The intersection of the sets A and B, is the set containing those elements that are in both A and B.

Test: Operations On Sets - Question 6

From the following Venn diagram, A ∩ (B ∪ C) is Detailed Solution for Test: Operations On Sets - Question 6

Correct Answer :- B

Explanation:- B = {3,5,6,7}   C = {7,8,9}

A = {2,4,6,8}

A⋂(B⋂C) = {6,8}

Test: Operations On Sets - Question 7

If= {x is a multiple of 3} and= {x is a multiple of 5}, then A - B is

Detailed Solution for Test: Operations On Sets - Question 7 Test: Operations On Sets - Question 8

From the following venn diagram, A ∩ B is Detailed Solution for Test: Operations On Sets - Question 8 A ∩ B = {4, 3}

Test: Operations On Sets - Question 9

In probability, the event ‘A or B’ can be associated with set:

Detailed Solution for Test: Operations On Sets - Question 9

Probability of event A or B

The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B) = 0. The probability that Events A or B occur is the probability of the union of A and B.

Test: Operations On Sets - Question 10

If A and B are two given sets, then∩ (∩ B)' is equal to
