Part e)
i) Getting 6 has a probability of 25%=4/16. So that's 1-5, 2-4, 3-3, 4-2.
ii) Getting any other result except 6 has a probability of 75% (that is, getting, 3, 4, 5, 7, 8, 9).
iii) It is certain that the score will be between 3 and 9 inclusive. Probability=1.
iv) It is impossible to get less than 3 or more than 9. Probability=0.
