They each take a hat out of the basket and put it on their heads without seeing the hat they selected or the hats the other men selected.

Tim is asked the same question, and he also doesn't know.
Finally, Jim is asked the question, and he does know.

Hint:
The hat is white. If Tom doesn't know his hat color then the other two men's hats cannot be both black otherwise he would know his is white.
