Explanation:

The answer given before me was not correct because there are more numbers. There are also odd 2-digit numbers in the 30s, since they all have the digit 3 in them. The correct set is: 13, 23, 31, 33, 35, 37, 39, 43, 53, 63, 73, 83, 93.

Answer:

{13,23,33,43,53,63,73,83,93}

Explanation:

These are the conditions given for the set.

  • The members of the set must 2-digit numbers, therefore it means they are in between 10 and 99.
  • The numbers are odd. Odd numbers are numbers that cannot be divided exactly by 2.
  • The numbers must have 3 in them.

So our goal is to get the set of all odd numbers between 10 and 99 that have 3 in them.

The elements of the set are:

{13,23,33,43,53,63,73,83,93}
