Problem 1157

Write the resulting set using the listing method.

{x | x is an old number between 11 and 19, inclusive}

 

Solution:-

 

The listing method listed all the elements of a set between braces { }.

The resulting set will contain all odd number between 11 and 19, inclusive. Remember, inclusive means that the endpoints are included.

An odd number is a integer that is not divisible by 2. The first odd number between 11 and 19, inclusive, is 11.

Therefore are four remaining odd numbers between 11 and 19, inclusive. These odd number are 13,15,17,and 19.

Therefore, the resulting set, written in listing notation, is {11, 13, 15, 17,19}
