Answer:
there are 48 possible seating arrangements.
Step-by-step explanation:
This can be calculated using the rule of multiplication, in which the number of options depends on the following cases:
3 * 1 * 2 * 2 * 1 = 12
Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
In this case:
At the same way, we can calculate the possible seating arrangements in the following cases:
3 * 2 * 1 * 1 * 1 = 6 Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
3 * 2 * 2 * 1 * 1 = 12
Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
1 * 3 * 3 * 2 * 1 = 18
3rd Row Seat Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle
So, there are 48 possible seating arrangements and it is calculate as:
12 + 6 + 12 + 18 = 48
