Answer:
120 ways
Step-by-step explanation:
This is a problem of combination.
We will solve this in steps.
First person : He has 5 ways to be seated in the row.
Second person : He has 4 ways to be seated in the row as one seat is already occupied now.
Third person : He has 3 ways to be seated in the row as two seats are already occupied now.
Forth person : He has 2 ways to be seated in the row as three seats are already occupied now.
Fifth person : He has only 1 place to sit in the row as four seats are already occupied now.
Hence total number of ways = 5 x 4 x 3 x 2 x 1 = 120
Hence there are 120 ways for five people to be seated together in a row
