3. Take a sphere and draw on it a great circle (a great circle is a circle whose centre is the centre of the sphere). There are two regions created. Here, I am referring to regions on the surface of the sphere. Now draw another great circle: there are four regions. Now draw a third, not passing through the points of intersection of the first two. How many re- gions? Here's the general question: How many regions are created by n great circles, no three concurrent, drawn on the surface of the sphere?

Using the Venn diagram in the figure, specify which region is described by the following statements. A 12 7 17 28 23 8 11 22 E 27 3 1 18 13 16 6. 31 29 /24 26 21 /19 9 20 30 32 15 10 25 14 D (a) AUBUCUDUE (b) ANBUCUDUE 2.

Eight blood types are shown by the eight regions of the Venn diagram shown here. Each circle represents one of three antigens: A, B or Rh. If A and B are both absent, the blood type is O. If Rh is present, the blood type is positive; otherwise, it is negative. The following table represents the blood types of 150 people. How many people have blood type B−?  Antigens Number of people A     60     B     27     Rh     123     A and B     12     B and Rh     17     A and Rh     46     A and B and Rh     9

A poll asked respondents if they agreed with the statement that colleges should reserve a certain number of scholarships exclusively for minorities and those age > 20. Hypothetical results of the poll are tabulated in the Venn diagram. How many of those age ≥ 20 agreed with the statement?
