consider the Monte Hall problem as discussed in lecture. Recall that a game show host(Monte Hall) gives a contest a chance to choose from three doors of which one is a new car and the other two are goats. After the contestant chooses a door, the game show host who knows what is behind all of the doors decides to open another door behind which a goat sits. The games show host. then, offers the contestant an opportunity to switch doors. For the purposes of this question, note the following:
1. The contestant initially selects door B
2.Game show host (Monte Hall) open door C behind which a goat sits
also note the following notation for events
1. Car A= the car is actually behind the door A
2. car B= the car is actually behind the door B
3. car C= the car is actually behind the door C
4. A= the host reveals a goat behind Door A
5.B=the host reveals a goat to be behind Door B
6.C= the host reveals a goat to be behind Door C
Given that the host reveals a goat behind Door C, what is the (conditional)probability that the car is actually behind door A [P(Car A| C)]?
