Question

A teacher assigns students to rooms in such a way that some of the rooms can be empty and more than one student can be assigned to a room. In how many ways can the teacher assign 3 students to 2 different rooms?

allabout · Answer

Is it 8?

2Â³=8, each student can be assigned to two rooms, without restrictions.

Edit: First, i thought there 3 different romms instead of 2.
C (3:2)=3 (ways to choose 2 students out of 3)
AB/C, AC/B, BC/A
However, the order of rooms matter and there 2 ways to assign 2 students together and 1 student in 2 separate rooms
R#1 R#2 
AB/ C 
 C/ AB
 
Total no. of ways=3*2=6

Two possible cases

1. All 3 in a single room - 2 cases
2. 2 in one room and 1 in one room. - 3C2 * 2 = 6 cases

Total = 8

Bhai,

I think the explanation goes like this:
For each student there are 2 choices: Room 1 or Room 2

Hence Total choices = 2 * 2 * 2 = 8.

giddi77 · Answer

Here is I think all the possibilities are:

Students: A, B, C
Rooms: 1, 2

ABC, None
None, ABC
A, BC
B, AC
C, AB
AB, C
AC, B
BC, A

Bhai · Answer

I meant hos did he get 3 over 2. we write 2^3. See how allabout did 3 little above 2. I think you can do it only if you copy from somewhere it was already formatted.
