Jay has two jobs to do, one after the other. Each attempt at job $i$ takes one hour and is successful with probability $p\_i$. If $p\_1 = 0.3$ and $p\_2 = 0.4$, what is the probability that it will take Jay more than 12 hours to be successful on both jobs?

I don't know how to start on this question, can someone give me some hints to help me start off? Thank you in advance.
