[1]	(website, assigned) 31 students were asked whether they used PCs and/or Macs, with these results : 25 students used only one of the two computer types 22 students used PCs 5 students used neither computer type I'm the number one in the Venn Diagram (a)(1 pt) Define in English the SETS (not numbers) P and M in the Venn diagram at the right, so that n(P) = 22 and n(P' M') = 5. If you define P and M as numbers, no credit.
	Let P = Let M =
	(b)(2 pts) Place numbers in the compartments of the Venn diagram at the right, so as to interpret the information given in the boxed problem above.
	(c)(1 pt) Assuming your answers to (b) above are correct, how many people used Macs?
	(d)(1 pt) Assuming your answers to (b) above are correct, how many people did not use Macs?

	The answer is between 1089 and 1090 ; this is so large than an exact answer can be given only using P(n.r), C(n.r) or factorial symbols
	(c)(Pg 448 #25)(1 pt) How many 7-digit telephone numbers can be formed if the first digit must be neither "0" nor "1" ? (thus, 234-5677 is a phone number, but 123-4567 is not)
	(the answer is between 5 million and 10 million)
	(d) (Website #10)(2 pts) On the Venn diagram at the right, shade in the portion that represents the set (A B)' C     These Venn Diagrams are so cute !
