A science teacher wants to prepare a resource pack for each of the 120 pupils in year 10.
She will need to photocopy 40 pages per pupil and give each pupil a folder to keep the pages in.
Photocopying costs 2p per page and folders are 70p each.
There is a similar resource available online for a one off cost of £175.
How much would she save by choosing the online option?
A group of 55 pupils were asked if they owned a phone or a tablet.
11 said they owned both
18 said they only owned a tablet
34 said they owned a phone
a) Draw a Venn diagram to show the information.
b) A student is chosen at random from the group.
