There is a truth teller (always tells the truth), a liar (always lies), and one that sometimes answers truthfully and sometimes lies. Each person knows who is who. You may ask three yes or no questions to determine who is who. Each time you ask a question, it must only be directed to one of the persons (of your choice). You may ask the same question more than once, but of course it will count towards your total. What are your questions and to whom will you ask them? ?
In all honestly I don't know where to start with this type of question. And really not looking for an answers but guidance on how to approach a problem like this.
The condtion that
Each person knows who is who Seem to me to be the important part of this, and this to me means I should start with trying to find the random person out, but what I cant figure is the starting question I should ask.
So I then tried to ask each person if there a liar, which has cause me confusion beacuse, if I ask A if he the lair, and he says yes,then he not the lair as the liar would say no therefore he telling the truth.
But if he says no then he could be telling the truth or a lie and doing this for the same concludes the same results, which confused me even more.
Is there a possibility someone could break this down a little, it would be much appreciated.
Also I am new here and not sure what tags I should tag, so sorry for the wrong input.
