The roster form of The set of odd natural numbers greater than or equal to 5 and less than or equal to 11 .
Lunna [17]

Answer:

{5, 7, 9, 11}

Step-by-step explanation:

Roster form just means list the elements of the set in the brackets.

It says the elements are greater than or equal to five and less than or equal to 11. So we start at 5 and end at 11.

We list {5, 7, 9, 11} because these elements follow the rule that they must be odd natural numbers. Natural numbers are the numbers you can count starting from 0 like {0, 1, 2, 3, ...}.
