Problem 1: Monte Hall, twisted

http://nostalgia.wikipedia.org/wiki/Monty_Hall_problem Explains the original Monty Hall problem and then the problem considering two contestants are involved.

Problem 1: Monte Hall, twisted

HW3.1.b Anand Gautam_ECE302Fall2008sanghavi This scenario is almost the same like the original problem. Just that your friend is kicked out by the host. The probability of you picking the car if you swap is 2/3 and not swapping is 1/3.

HW3.1.b Steve Streeter_ECE302Fall2008sanghavi The best way to look at this part of the problem is to divide it into 3 events. A: [You-Car,Friend-Goat], B: [You-Goat,Friend-Car], C: [Both picked goats]. From there you can use the condition that your friend was kicked off. So, for event A, if you switch, P(winning) = 0. Not switching: P(winning) = 1. You can determine the probabilities of other events in the same fashion.

Problem 4: Colored Die

HW3.4.a Seraj Dosenbach_ECE302Fall2008sanghavi

HW3.1.b Anand Gautam For part a, the chance of drawing each die is independent of the other one. So the probability of red on the first roll is just the product of the chance of drawing a red face on each die. hope that makes sense.

HW3.4.b Joon Young Kim_ECE302Fall2008sanghavi

[HW 3.4.c Junzhe Geng] In this problem, we are asked to find the possibility of selecting a 3-red-face die when the first three rolls all give red faces. which is to find P(3-R-F|3R) according to formula: P(3-R-F|3R)=P(3-R-F n 3R)/P(3R), P(3-R-F n 3R) is easy to find. to find P(3R), we need to calculate each cases: selected 1-R-F(one red face), 2-R-F, or 3-R-F thus, P(3R)=P(3R n 1-R-F)+P(3R n 2-R-F)+P(3R n 3-R-F) each of those are not hard to find. my final result was 3/4. Hope it is right.
