The way i approached it is following:
We have total of 12 people.
M1 W1 M2 W2 ...... M6 W6
number of ways to choose 4 people out of 12 is 12C4 = 495
Let's say first place goes to M1.
second place can go to anybody except for W1. number of ways = 10.
third place can go to any of the remaining 8 people. number of ways = 8.
fourth place can go to any of the six eligible people. number of ways = 6.
I am not sure whether this is the right approach. If yes, how should i proceed further?
for every person who doesn't try because he is
afraid of loosing , there is another person who
keeps making mistakes and succeeds..
