Probability of choosing a student with blood group O:
- Total number of students = 40
- Number of students with blood group O = 14
- Probability = Number of students with blood group O / Total number of students
- Probability = 14/40 = 7/20 = 0.35

Probability of choosing a student with blood group AB:
- Number of students with blood group AB = 6
- Probability = Number of students with blood group AB / Total number of students
- Probability = 6/40 = 3/20 = 0.15

Probability of choosing a student with blood group B:
- Number of students with blood group B = 9
- Probability = Number of students with blood group B / Total number of students
- Probability = 9/40 = 9/40 = 0.225
Therefore, the probability of choosing a student with blood group O is 0.35, with blood group AB is 0.15, and with blood group B is 0.225.
