doesn't have either... or

[navi tasan]

1) If he doesn't have either his ID or money, he is in trouble.
2) If he doesn't have his ID or money, he is in trouble.
3) If he doesn't have either of them, he is in trouble.

Do these mean:
a) He needs at least one of the two
or
b) He needs both of them

Gratefully,
Navi.

I would say a.

 

[Barb_D]

There is room for ambiguity.
Missing either of them is a problem. (He needs both)
or
Not having at least one of them is a problem.

 

[MikeNewYork]

I don't see "either" as ambiguous.

 

[Raymott]

To me, only 3 is ambiguous.
