To find 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 need to identify the even numbers in that range.
The even numbers up to 10 are: 2, 4, 6, 8, and 10. Among these, the even numbers that are less than 5 are:
- 2
- 4
Thus, the correct outcomes for the event of rolling an even number less than 5 are {2, 4}. Therefore, the answer is:
{2, 4}
