Given:

Five persons including two adults and three children, sit in a line for photograph.

To Find:

How many different arrangements can be done if children occupy the end

seats and middle seat?

Step-by-step explanation:

• Here the concept of permutations and combinations can be used . In these types we first select things and then arrange them.
• Here as there are 5 persons and 3 children who will occupy the end and middle seat , so we will first arrange the children.
• The 3 children can be arranged in factorial(3) ways which will give us $6$ ways.
• As both adults can be arranged in 2 ways .
• Total no of ways to arrange 3 children and 2 adult will be
• $=6\times 2 \\=12$

The final answer will be 12
