    Hi again Gale,

    Actually, could your resend your post to Teacher-Talkmissinglink@learner.org? Or if you'd like, I'll send it on for you, but if I do it will look like it's coming from my address instead of yours.

    Interesting problem, by the way!


          Hello: I wanted to discuss the various methods used to solve the following puzzle. So to start the discussion I will present the puzzle and then discuss the solution with anyone who is interested. Here goes.

      "Salesmen lie 4/7 of the time. We pick a tree in the forest, at random, and ask the salesmen (three of them) to tell us what kind of a tree it is. All three agree that it is an oak. The probability the tree is an oak is 9/73. What portion of the trees are oaks?"

      Dear Gale,

      Sure, go ahead! Anything of interest to math teachers is fine for this forum.

        would it be appropriate to pose a question about a probability puzzle?
