sets? what are
they ?​

Answer 1

Answer:

3 ways

they are:-

I. Tabular Form:

Listing all the elements of a set, separated by commas and enclosed within curly brackets {}.

Example:

A={1,2,3,4,5},B{2,4,6,⋯,50},C{1,3,5,7,9,⋯}

II. Descriptive Form:

State in words the elements of the set.

Example:

A= Set of first five natural numbers.

B= Set of positive even integers less than or equal to fifty.

C= Set of positive odd integers.

III. Set Builder Form:

Writing in symbolic form the common characteristics shared by all the elements of the set.

Example:

A={x:x∈N∧x⩽5} N = Natural numbers

A={x:x∈E∧0<y⩽50} E = Even numbers

A={x:x∈O∧x>0} O = Odd numbers
