Answer 1

Answer:

It is a method of writing sets using { } and separate the units using comma.

Eg1.

Set of 1st three natural number

{1,2,3}

Eg2.

Set of your first 4 favourite colours

{Green,red,blue,black}

Rule method:

The rule method gives us information about the elements in the sets

Example 1.

If B= {1,2,3,4,5}

Then B = {x| x is a natural number less than six}

Example 2.

If C= Saturday Sunday

Then C= { x| x is a day of the week the week beginning with the letter 's'}

Hope it's clear now.
