(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1 and 2 take turns shooting at a target. Each time 1 shoots he hits the target with probability p_{1}; 2 hits it with probability p_{2}each time. 1 shoots first. They stop when the target has been hit twice. What is the probability that...

a) The first hit was by 1 ?

b) Both hits were by 1?

c)Both hits were by 2?

2. Relevant equations

Conditional probability?

3. The attempt at a solution

Actually I'm a little (very) rusty. I took probability a year ago, and I just don't know how to start it.

I'm totally lost here.

Would appreciate any help.

Thanks,

Roni.
