JamieThank you for your email. I am sorry that you were unhappy with the examination paper and I hope that the information below will be of some assistance to you. I am aware of the press and media coverage which has just occurred in relation to this paper, particularly in relation to Question 7 and 8. We have issued a press statement to the media confirming that there was no error in Question 7 and that Question 8 was within the prescribed syllabus for the subject. Comments and observations regarding test instruments are an intrinsic part of the feedback that we would expect to receive in any year. The well-tried methodology in place to deal with issues that arise in the course of the examination process is the development of the marking scheme by the Chief Examiner and his college of examiners in light of the circumstances of that year’s examinations. All observations received in relation to a subject are reviewed by the Chief Examiner in the context of preparing the marking scheme for that subject. I will ensure that your comments below are sent to the Chief Examiner. I hope that the remainder of the examinations will go well for you. Thank you again for taking the time to contact us. Kind regards,

As for probability, I've come across two questions in class that they might ask to trick you (I'm in the top class in my school and even still only 2/3 of us got it right): 1) If the odds of having a boy and having a girl are equally likely, and a certain family have 2 children, one of which is a boy, find the odds that the second child is a boy. 2) A dice is rolled THREE times... The first question is 1/3 - many people assume it's a half but the reason its actually 1/3 makes sense: Normally there are four possibilities - {B,B}, {B,G}, {G,B}, {G,G} If one is already revealed to be a boy, that rules out the last bracket leaving 3 options and only 1 has two Boys. The second question threw people off who do sample spaces. The best way I found to do this one is to roll one dice and multiply that probability by a sample space. I think a question like this is in Discovering Maths. If they ask for probability of "all 3 adding up to (number, or range of numbers)", you may have to draw the sample space 6 times, adding one to all values in the first, 2 to all values in the second, etc. Add up the number of combinations that fit the question and divide by 216 (there are 6^3 possibilities). Lastly, if they ask you for a coin toss or something similar and ask "what are the odds of P(n) happening exactly x amount of times", the formula is [(Total No. times) C (No. times P(n) occurs)]*(Prob of P(n) occuring)^(no. times P(n) occurs)*(Prob of P(n) not occuring)^(No. times P(n) doesn't occur) It looks neater when all those brackets are replaced with symbols... That's all I can think of at the moment...
