I think the robbins way
is right. But i couldnt
under stand why did
he multiply the result
by 2

the chances are
none in the fist box
and all in the other
box=4C0=1
1 in fist and 3 in
second=4C1=4
2 in first and 2 in
second=4C2=6
3 in first and 1 in
second=4C3=4
4 in fist and none in
second=4C4=1

so net chance is
4C0+4C1+4C2+4C3+4C4=16

If the letters are thought to be unique than the answer is: 2*2*2*2=8
If the letters are thought to be identical(as in spam mails) than the answer is:
(5,0,0) (4,1,0) (3,2,0) (2,3,0) (1,4,0) (0,5,0)
(4,0,1) (3,1,1) (2,2,1) (1,3,1) (0,4,1)
(3,0,2) (2,1,2) (1,2,2) (0,3,2)
(2,0,3) (1,1,3) (0,2,3)
(1,0,4) (0,1,4)
(0,0,5)
1+2+3+4+5+6 = 21 ways

You are driving along in your car on a wild, stormy night, it's raining heavily, when suddenly you pass by a bus stop, and you see three people waiting for a bus: An old lady who looks as if she is about to die. An old friend who once saved your life. The perfect partner you have been dreaming about. Which one would you choose to offer a ride to, knowing very well that there could only be one passenger in your car? This is a moral/ethical dilemma that was once actually used as part of a job application. * You could pick up the old lady, because she is going to die, and thus you should save her first; * or you could take the old friend because he once saved your life, and this would be the perfect chance to ! pay him back. * However, you may never be able to find your perfect mate again.
