You must draw the vann diagram - Two overlapping circles, one circle is A (Coffe), the opposite is B (Hot Tea). Label them as such. Enclose the circles in a rectangle. Put the numbers for your venn diagram: four in circle A, five in circle B, two in which the 2 circles overlap, (the intersection of A and B i.e. contributors of each A and B) a million external the 2 circles however within the rectanagle. five - A U B (A union B) method the entire factors of A and B. Add up the entire factors in circle A, circle B and within the intersection of the 2 (in which they overlap) - four + five + two = eleven . It represents people who like espresso or scorching tea (or each) 6 - A n B (A intersection B) method factors in each A and B, so it is in which the circles overlap i.e. two. It represents people who liek each tea and occasional 7 - A? and B? method no longer in A and no longer in B. So its no longer side of both A or B so it is the quantity external of the circles however within the rectangle i.e. a million. It represents people who like neither tea or espresso eight - what's v?

Much better if you search on google since they will have diagrams.
Hard to explain without it.
