What examiners said
This proved to be a challenging question and relatively few candidates gained full marks. Many were able to identify the centre and obtained something of the formz (–2 + i) 3. A few candidates omitted the modulus signs, a number stated and equation instead of an inequality and some had the incorrect radius. Many did not state a second inequality at all. A common mistake was to use Im(z) ≤ i.

Most candidates were able to achieve full marks on this question. Candidates were able to square x + iy correctly and then equate the real and imaginary parts to −4 and 6 5 respectively. They were then able to solve the simultaneous equations, finding the correct quartic and solving for the correct values for x and y. Those candidates who did not achieve full marks either did not give two solution...

The majority of solutions were fully correct, with the probability distribution table clearly shown and with some supporting work. Very few candidates had probabilities that did not add to 1. The most common error was to omit P(X = 0) from the table. A small number of candidates presented decimal answers, and these were not always the accurate conversion of a stated fraction.
