Answer

B∩C={a,l}B \cap C = \{a, l\}

Step-by-step solution

3 steps

Here's the solution for question 13a:

a)
Given sets:
B={letters of the word ’ball’}B = \{\text{letters of the word 'ball'}\}
C={letters of the word ’small’}C = \{\text{letters of the word 'small'}\}

  1. List the elements of set B.

    The unique letters in the word 'ball' are b, a, l.

    B={b,a,l}B = \{b, a, l\}
  2. List the elements of set C.

    The unique letters in the word 'small' are s, m, a, l.

    C={s,m,a,l}C = \{s, m, a, l\}
  3. Find the common elements (intersection) of B and C.

    The elements that are present in both set B and set C are a and l.

    B∩C={a,l}B \cap C = \boxed{\{a, l\}}
