Answer:
(a) 76 students drink coffee.
(b) 150 students drink coffee, tea, or both.
(c) 38 students do not drink both tea and coffee.
Explanation:
This question requires an analysis of Venn diagrams.
(a) The two circles are shared, but only 76 students drink coffee.
(b) I'm pretty sure this is a trick question. It says "how many drink tea OR coffee OR both?" probably meaning that they want you to count everyone besides the 38 who do not drink either. This could be 28, but I am sure that it is 150.
(c) As seen outside of the Venn diagram, 38 do not drink either coffee or tea.
