| The Guy at the Bar |
One of the questions discussed in my Statistics lecture today was rather funny and interesting. Here's the question:
There are 10 men sitting at a bar. 8 are drunk and 2 are sober. One of them is really cute and you want to go talk to him, but first you sit at the bar and check them out for 10 minutes. From previous experience, you know that if he is drunk, then the probability he goes to the bathroom in the next 10 minutes is 0.7 but if he is sober, the probability he goes to the bathroom in the next 10 minutes is 0.1. He indeed goes to the bathroom in the next 10 minutes. What is the probability that he is sober?
Know the answer? You go figure and tell me! |
