I have a problem to solve where
38 people were asked if they had visited Thailand, Brunei or Indonesia. 8 have to Thailand & Brunei, 15 have been to Brunei & Indonesia, 11 have been to Thailand & Indonesia.
Given that 18 have been to Thailand, 19 to Brunei, 26 to Indonesia.
Draw a Venn diagram to show the following
a) How many people went to all the three countries???
b) none of the three countries.
I am having facing a bit of difficulty when calculating the number of people who went to all the 3 countries???
Cheers
