a. Joe's personal probability for North Carolina is 0.1

Joe's personal probability for Duke is 0.2

b. Joe's personal probability that 1 of the 12 teams other than Notre Dame, North Carolina, and Duke will win the tournament is 0.65

Step-by-step explanation:

a. According to the given data, to calculate Joe's personal probability for North Carolina we would have to make the following calculation:

Joe's Personal P (North Carolina Wins) = Joe's Personal P (Notre Dame wins) * 2

Joe's Personal P (North Carolina Wins) = 0.05*2

Joe's Personal P (North Carolina Wins) = 0.1

Joe's personal probability for North Carolina is 0.1

To calculate Joe's personal probability for Duke we would have to make the following calculation:

P (Duke wins) = Joe's Personal P (Notre Dame wins) * 4 = 0.05*4 = 0.2

Joe's personal probability for Duke is 0.2

b. To calculate Joe's personal probability that 1 of the 12 teams other than Notre Dame, North Carolina, and Duke will win the tournament we would have to make the following calculation:

P (1 of the 12 teams other than Notre Dame, North Carolina and Duke wins) = 1 - P (Notre dame or north north ca or duke wins) = 1 - (0.05+0.1+0.2) = 1-0.35=0.65

Joe's personal probability that 1 of the 12 teams other than Notre Dame, North Carolina, and Duke will win the tournament is 0.65
