To determine the outcomes for the event of rolling an even number less than 5 on a regular 10-sided number cube (which has the numbers 1 through 10), we can identify the even numbers within that range.
The even numbers on the cube are: 2, 4, 6, 8, and 10. Among these, the even numbers that are less than 5 are: 2 and 4.
Therefore, the outcomes for the event of rolling an even number less than 5 are:
{2, 4}
So the correct response is:
{2, 4}
