Question 560798
Arthur normally wins 1 out of every 3 backgammon games he plays.  In other words, the probability that Arthur wins when he plays backgammon is 1/3.  Suppose Arthur plays 4 games.  What is the probability that he will win 3 and lose only one?

Binomial Problem with n = 4 and p(lose) = 2/3

P(x = 1) = 4C1*(2/3)*(1/3)^3 = 0.0988
