there are three employees say A,B,and C and 2 offices say X , and Y
now A can chose any from x and y in 2c1=2 ways
similarly B in 2 ways and C in 2 ways
so total # of ways=2*2*2=8

it will come down to basics
i mean
1 ----------- 2
ABC ----------- 0
0 ----------- ABC
AB ----------- C
C ----------- AB
BC ----------- A
A ----------- BC
CA ----------- B
B ----------- CA

take A,
he infact can make 8 choices.

Am i missing some basics here? (may be wrong choice of word)

Every employee has to go to one of the office. so if A choses not to go to office x then that means he has chosen to go to office y.

So consider following choices for A:
1. go to x (means do not go to y) = do not got y (means go to x).
2. go to y(means do not go to x) = do not go to x (means go to y).
3. do not got to x and Y (THIS CONDITION IS NOT POSSIBLE)
