`A cap B`

Answer

To solve the problem of finding the intersection of sets A and B, we will follow these steps:

### Step 1: Define Set A
Set A is defined as the set of letters from the word "daily".
- The letters in "daily" are: D, A, I, L, Y.
- Therefore, Set A = {D, A, I, L, Y}.

### Step 2: Define Set B
Set B is defined as the set of letters from the word "doll".
- The letters in "doll" are: D, O, L.
- Therefore, Set B = {D, O, L}.

### Step 3: Find the Intersection of Set A and Set B
The intersection of two sets, denoted as A ∩ B, consists of elements that are common to both sets.
- We will compare the elements of Set A and Set B:
- Set A = {D, A, I, L, Y}
- Set B = {D, O, L}

- The common elements between Set A and Set B are:
- D (present in both sets)
- L (present in both sets)

### Step 4: Write the Intersection
Thus, the intersection of Set A and Set B is:
- A ∩ B = {D, L}.

### Final Answer
A ∩ B = {D, L}.
