Passage / Comprehension
Players A, B, C throw in order until someone throws 6. Player A uses a fair die; B and C throw 6 with probabilities p_1 and p_2, respectively.
Find if all three players are equally likely to win.
Options:
Answer:
C
Solution:
Equality gives p_1=p_2(1-p_1) and (1-p_1)(1-p_2)=3/5. Thus p_1=1/5, p_2=1/4, so p_1:p_2=4:5.
