Imagine a fictional game show whose host is named Minty Hill. Here's how the game works: Minty shows you 25 curtains. Prizes are placed randomly behind the curtains. Behind 5 of the curtains is a fortune in gold. Behind each of the other curtains is a bag of pennies. You choose one of the curtains. After you choose a curtain, Minty always opens a curtain that has only pennies behind it, but he does not open the curtain that you chose. If he has more than one option, he chooses among them uniformly at random. Now imagine that you are playing the game for real. You chose curtain 1. Minty opened curtain 2, showing a bag of pennies. Curtains 1 and 3-25 are still closed. Minty asks whether you would prefer what is behind one of the other curtains. What is the probability that there is gold behind Curtain 1? Question 40 1 pts A room contains several urns. 90 urns contain two gold balls. 7 urns contain one gold ball and one silver ball. 5 urns contain two silver balls. You choose an urn at random and then draw two balls from the urn. If the first ball you draw is silver, what is the probability that the second ball you draw is silver?
