Let U= 1,2,3,4,5,6,7,8,9,10

{12345 n 34567
Thank you

which elements are in both sets?

{3,4,5}

Don't get sloppy with your notation, or things will get confusing as the problems get more involved. Your second line is just nonsense, but it's easy to figure out what you meant in this case. (I think!)

To find the intersection of the sets {12345} and {34567}, we can compare the elements in both sets and find the common elements.

Here's how you can do it:

1. Write down the elements of the first set: {12345}.
2. Write down the elements of the second set: {34567}.
3. Compare the elements in both sets. Look for any elements that are present in both sets.
- In this case, we can see that the element 3 is present in both sets.
4. Write down the common elements to find the intersection: {3}.

Therefore, the intersection of {12345} and {34567} is {3}.
