Answer 2

Explanation:

Roster method is also known as roster form in sets. We can see this in chapter-1 (Name of chapter-Sets) of 11 standard.

This word is seems to be very dangerous, but it is very simple. First of all we have to know that what are sets? The sets are the collection of well defined elements (or elements that will never change their values e.g. 1, 2, a, Jersey, etc.) enclosed within curly brackets.

These sets are written in two forms-

a. Roster Form

b. Set Builder Form

Roster Form- When the elements are written in value.

Set Builder Form- When the elements are written in statements.

Lets take an example-

Q. Write a set of even natural numbers less than 11.

Sol. Roster form {2, 4, 6, 8, 10}

Set Builder Form {x : x € N, x÷2=0, x<11}

Q Rational numbers

R Real numbers

Z Integers)
