This might seem very basicto some of you, I'm just not a math person, and wondering if someone could help me with this:(adsbygoogle = window.adsbygoogle || []).push({});

A, B, and C shoot at a target in this order: ABCABCABCABC... until the target is hit. Each shot and each shooter is independent of each other. The probability that A hits the target is 4/5. The probability that B hits the target is 4/5. The probability that C hits the target is 1/3. What is the probability that the first person to hit the target is B?

Could anyone explain how you do this?
