The drivers are given a choice about how to cross a river in a town. The choices are either to use the bridge or the tunel. Both of the two options have the same length and take the same time. Let's suppose that when it is raining 4 out of 5 drivers prefer to use the tunnel. Out of 60 cars we observed that 16 used the bridge. We would like to interview them, so we can explore the reason for this decision. If we stop at the other band of the river 9 drivers, what is the probability that 2 of them used the bridge
