Players A and B take turns rolling two fair dice. Player A wins if he rolls a sum less than or equal to 5. Player B wins if she rolls a sum greater than or equal to 6. The game continues until someone wins.
(a) Assuming that Player A goes first and assuming that the rolls of the dice are independent
of each other, find the probability mass function for X where X is the random variable
which counts the number of rolls it takes for B to win.
possibilities: 2 dice 6^2 = 36possibilities
A: 10/36 chance of winning
B: 26/36 chance of winning
stuck on the cases for when x=1,2,..k

Notice that $P(A)^c=P(B)$. Then, you can simply create geometric distribution using those.
Will provide the answer if you comment what you have deduced, using the above fact.
