one each

[Progress]

We'll then hear three talks: one each from Mr.A, Ms B and Mr C.
In this case, cay you say each one instead?

Would you please teach me the difference?
Thank you very much.

One each- this just emphasises that each person will only give one talk, though with such a small number of people, I can see no great need for the emphasis.

Thanks Tdol. In this case, each one is OK, right?

No, you can't use "each one" there. That would mean that each of the three people will give each of the three talks -- nine talks in total.

Oh!! I see. Thanks MikeNewYork

We'll then hear three talks: one each from A,B and C, which means one of the three talks respectively from A,B and C.

each one's case means each of THE three talks, GREAT
