2.. Let us revisit the RedGreen game we played in class. There are three people playing the game, and they are all able to make logical deductions from the information they have. Person 1 has the letter \"R\" on his back. Person 2 has the letter \"R\" on his back. Person 3 has the letter \"G\" on his back. Each person sees the letters that the other two have on their backs, but does not know his own letter. A reporter declares in front of all of them \"at least one of you has an 'R' on their back.\" He then asks person 1 \"what letter do you have on your back?\" Persons 2 and 3 hear person 1's answer. The reporter then asks person 2 \"what letter do you have on your back?\" Person 3 hears person 2's answers. The reporter then asks person 3 \"what letter do you have on your back?\" Remember that a erson answers \"R\" or \"G\" onl if he is certain of his answer. y Otherwise, he answers \"I don't know.\" (a) What does person I answer? Explain. (b) What does person 2 answer? Explain. (c) What does person 3 answer? Explain
