the question says "if John goes through the doorway after Barbara" so how can john go before barbara

yeh thats y u divide 8! by 2

 

[Etude]

dividing by 2 implies you can have john first then barbara or barbara first then john. the qn states john goes thru after barbara, that means barbara first then john so how can the 2 swap.

 

[hodarrenkm]

all possible ways = 8!
john goes before + john goes after = 8!
therefore john goes after = 8!/2

another way of doing this is
BJXXXXXX
BXJXXXXX
BXXJXXXX...
BXXXXXXJ
6! X 7

XBJXXXXX
XBXJXXXX
XBXXJXXX...
XBXXXXXJ
6! X 6

last set would be

XXXXXXBJ

overall = 6!(7+6+5+4+3+2+1) = 20160
