One way to win in a game with two dice is to roll a sum of six before getting a sum of seven. (Anything else that happens ” sums of - are ignored.)

  1. How many ways are there to get a sum of six?

  2. How many ways are there to get seven?

  3. How many possible outcomes are important in this problem?

    Do the other sums have any effect on the probability of winning the game?

  4. What is the probability of getting a six before a seven?

    What fraction of the important outcomes are sums of six?
