Help with Venn diagrams

Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Someone please help me complete the Venn diagram with the data that I have been given
2. (Original post by JackT2000)
Here's the question
3. When it says 32 bought a drink, that includes the 11 that bought both, so you need to take 11 from 32
so 21 only bought drinks
you need to do the same with the popcorn

The question says 11 people bought both popcorn and a drink that's where you start, which you got right as you but it in the intersection of the diagram
next to you know 32 people bought a drink, 11 of those are already accounted for as they are in the middle of the diagram ( 11 out of the 32 bought a drink too but they still count as buying a drink)
as 11 are accounted for you need to find the remaining number of people who bought a drinkso you need to do 32-11 which is 21 that means 21 bought only a drink
and you do the same with popcorn

Is it all right now?

36-11 is 25 not 24, apart from that is should be right
and if you add everything together it should add the the total number of people surveyed
8. Are you in the top sit of your school? to be honest, this is super easy.
it just a easy peasy probability question.
