1 Here is a Venn diagram.
(a) Write down the numbers that are in set
(i) A ∪ B
(ii) A ∩ B
One of the numbers in the diagram is chosen at random.
(b) Find the probability that the number is in set Aʹ
7 Each student in a group of 32 students was asked the following question.
“Do you have a desktop computer (D), a laptop (L) or a tablet (T )?”
Their answers showed that
19 students have a desktop computer17 students have a laptop16 students have a tablet 9 students have both a desktop computer and a laptop11 students have both a desktop computer and a tablet 7 students have both a laptop and a tablet 5 students have all three.
(a) Using this information, complete the Venn diagram to show the number of students in each appropriate subset.
(3)
One of the students with both a desktop computer and a laptop is chosen at random.
(b) Find the probability that this student also has a tablet.
(a) Work out an estimate for the distance the car travelled in the first 10 seconds.Use 5 strips of equal width.
(b) Is your answer to (a) an underestimate or an overestimate of the actual distance?Give a reason for your answer.

25 The diagram shows an oil tank in the shape of a prism.
The cross section of the prism is a trapezium.
The tank is empty. Oil flows into the tank.After one minute there are 300 litres of oil in the tank.Assume that oil continues to flow into the tank at this rate.
Work out how many more minutes it takes for the tank to be 85% full of oil.(1 m3 = 1000 litres)
