Mathematical Formulae and Statistical Tables (Green), calculator
Candidates may use any calculator permitted by Pearson regulations. Calculators
must not have the facility for symbolic algebraic manipulation, differentiation and
integration, or have retrievable mathematical formulae stored in them.
Instructions
•• Use black ink or ball-point pen.
•
If pencil is used for diagrams/sketches/graphs it must be dark (HB or B).
Fill in the boxes at the top of this page with your name,
••
centre number and candidate number.
Answer all questions and ensure that your answers to parts of questions are clearly labelled.
Answer the questions in the spaces provided
•
– there may be more space than you need.
You should show sufficient working to make your methods clear. Answers without working may
•
not gain full credit.
Values from statistical tables should be quoted in full. If a calculator is used instead of tables the
•
value should be given to an equivalent degree of accuracy.
Inexact answers should be given to three significant figures unless otherwise stated.
Information
•• A booklet ‘Mathematical Formulae and Statistical Tables’ is provided.
•
The total mark for this part of the examination is 50. There are 6 questions.
The marks for each question are shown in brackets
– use this as a guide as to how much time to spend on each question.
Advice
•• Read each question carefully before you start to answer it.
•
Try to answer every question.
Check your answers if you have time at the end. Turn over ►

1. A student is conduct ing an experiment to study the probab ilit ies of outcomes in a card game.
She defines two events:
DO NOT WRITE IN THIS AREA
• A: The player w ins the first round
• B: The player w ins the second round
It is known t hat:
• P(B ) = p,where0 < p < 1
• P(A) = 2p
• Events A and B are mutua lly excl usive
(a) Write down an inequal ity invo lving p.
(1)
(b) Find the range of possible va lues fo r p.
(2)
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
Now suppose instead that:
• P(A U B) = 0.7
• P(A n B) = 0.2
(c) Are the events A and B mutua lly exclus ive in th is case? Justify your answer.
(1)
(d) Find:
• P(A)
• P(B IA)
• P(A' n B ')
