Logicians bar. All in the group want a beer. Assuming they are all telling tge truth, the 1st one would have said no if she dud not want a beer, but said I don’t know meaning she did not know about the other 2. The second said same thing and was not sure about the third person, so she wants a beer. The third person figured out the first 2 want beer and so does she.
So, yes.
