Homework Help: Statistics

Posted by BadatStat on Tuesday, July 3, 2012 at 6:22am.

A game at the state fair has a "guesser" guess the month of your birth. You win a prize if he misses your month by more than 2 months (for ex: if you were born in April, and he guesses February, he wins; if he guessed January, you win). For simplicity, assume that all 12 months are equally likely birth months, and that the results of all games are independent.

a. In the course of a night, the guesser has 6 players. What is the distribution of the number of players who win?

b. If the guesser has 6 players, find the probabilty that he wins more than half of those games.

Please help.. I have no idea what I'm doing T_T
