Your question is First-Roll Wins Probability. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Two players take turns rolling a fair six-sided die. The first player to roll a 6 wins. What is the probability that the first player wins?
Express the answer as an exact fraction and decimal. Show how you account for repeated rounds in which neither player rolls a 6, and state the assumptions about independence and indefinite play.
