SUMMARY
The problem involves selecting 3 men and 3 women from 5 married couples while ensuring that exactly 2 of the selected couples are married to each other. The solution begins by selecting 2 couples from the 5 available, which can be done in 10 ways. Next, one man is chosen from the remaining 3 men, and one woman is selected from the 2 women who are not his spouse. This results in a total of 60 valid combinations for the selection process.
