Answer 1

Part A.)

Since we can't choose the same course twice, and a choice like 650, 649 is the same as 649, 650, we have the total list is as follows:

1. 684, 670
2. 684, 649
3. 684, 641
4. 684, 650
5. 670, 649
6. 670, 610
7. 670, 650
8. 649, 610
9. 649, 650

Part B.) Assuming that each choice is equally likely to be made (that is the student is not inherently biased towards a particular subject or subjects), we have that:

Since we can't choose the same course twice, and a choice like 650, 649 is the same as 649, 650, we have the total list is as follows: 1. 684, 670 2. 684, 649 3. 684, 641 4. 684, 650 5. 670, 649 6. 670, 610 7. 670, 650 8. 649, 610 9. 649, 650 Assuming that each choice is equally likely to be made (that is the student is not inherently biased towards a particular subject or subjects), we have that: P(Choice = (649, 650)) = # of favourable outcomes/# of Total Outcomes = 1/9
