Marks were awarded in each question for each of the following.  In general, partial marks were deducted for arithmetic errors and no marks were deducted for carrying over the wrong value from a previous part of the answer.

See the exam solutions for common errors and the marks that were deducted for each of these errors.

Q.2

- 1 for Rayleigh distribution
