In how many ways can you arrange 6 people in 3 cars , such that there is 1 person in each car minimum
Looks pretty simple but it's pretty complicated, I tried a lot my answer ain't matching
Please help , Thanks |
Not sure how you would get there purely mathematically, I would just set up a system to be methodical in your approach. Trick is to avoid duplicates while, still getting the different combos of the same distribution.
Eg 114 can go 3 ways
141 411
Work through all combos starting with 1, then 2 and 3. Once there you will start getting mirrors of the same thing |
The possible combinations are :
4 1 1
3 2 1
2 2 2
Further I tried to solve it through permutation and combination but i failed to get the answer

Dont forget that every person is unique |
I feel this question is missing some details on how to perceive the persons
Anyone who tries to solve it , the correct answer is *540* |
Oh okay I got the answer
This was an onto function
And after that simply using onto function formula
nC0*n^m + nC1*(n-1)^m + nC2*(n-2)^m.. until it ends
Thanks :D |
