Question 977788: A and B play a game as follows: an ordinary die is rolled and if a “six” is obtained then A
wins and if a “one” is obtained then B wins. If neither a six nor a one is obtained then the
die is rolled again until a decision can be made. What is the probability that A wins on (i)the first roll and (ii) the second roll?
