A set which is not a finite set is called an infinite set. Also, the solutions and explanations are included. (Georg Cantor) In the previous chapters, we have often encountered "sets", for example, prime numbers form a set, domains in predicate logic form sets as well. If you like this resource, then please rate it and/or leave a comment. Note that in the second identity, we show the number of elements in each set by the corresponding shaded area. 2.

C) 30 D) 10 Answer:- n(C U T) = 90; n(T) = 65, n(C) = 35 So n(C U T) = n(C) + n(T) – n(C ∩ T) = 90 = 35 + 65 – n(C ∩ T) n(C ∩ T) = 100 – 90 = 10 so option number (D) is right. Solution. (ii) Let B = set of all odd positive Integers = {1, 3, 5, 7, 9,…} Here B is not a finite set. (Caution: sometimes ⊂ is used the way we are using ⊆.) Set theory is also the most “philosophical” of all disciplines in mathematics. Ling 310, adapted from UMass Ling 409, Partee lecture notes March 1, 2006 p. 4 Set Theory Basics.doc 1.4.
