Solve the ff:

The lone bus traveling on Forgettable route is never on time leaving its terminal; it leaves either early or late. If it leaves early this time then there is only a 15% chance that it would leave early the next time. On the other hand, if it leaves late this time then there is a 70% chance that it would leave early the next time. Given that it leaves early this time, what is the probability that it leaves exactly once the next two times it leaves the terminal? 2 points
