Answer:
A. The probability of getting a prize (of either $1200 or $120) if you switch your guess after Montana opens one door is 0.6
B. The fair price you should be willing to pay to play this game is $264
Step-by-step explanation:
A. According ot the given data Let A be the event of wining a prize
Let B the event of losing a prize
P(A)=2/6C1=2/6=1/3
P(B)=1-P(A)=2/3
Hence, after opening the door:
P(A I B)=P(A∩B)/P(A)
P(A∩B)=2/5
P(A I B)=2/5/2/3
P(A I B)=0.6
The probability of getting a prize (of either $1200 or $120) if you switch your guess after Montana opens one door is 0.6
B. The fair price you should be willing to pay to play this game=∑(expected prize) probability
The fair price you should be willing to pay to play this game=1200*1/5 + 120*1/5 + 0*3/5
The fair price you should be willing to pay to play this game=$264
The fair price you should be willing to pay to play this game is $264
