Question

N how many ways 7 different people can sit in 4 buses if any people can sit any bus ?

Answer 1

Answer-

If we would ask all the 7 persons to go and sit in the buses one by one, every person would have 4 choices. They may sit in any one of the 4 buses.

So, the number of ways in which one person can sit in 4 buses = 4.

Also it would be same for remaining 6 persons.

So, the total number of ways in which 7 persons can sit in 4 buses = 4*4*4*4*4*4


So, the answer is 16384
