Problem 2.1 Which of the following are sets? Assume that a proper universal set has been chosen and answer by listing the names of the collections of objects that are sets. Warning: at least one of these items has an answer that, while likely, is not 100% certain. (i) A = {2,3,5,7,11,13,19} (ii) B={A,E,I,O,U} (iii) C={√x : x < 0} (iv) D = {1,2,A,5,B,Q,1,V} (v) E is the list of first names of people in the 1972 phone book in Lawrence Kansas in the order they appear in the book. There were more than 35,000 people in Lawrence that year. (vi) F is a list of the weight, to the nearest kilogram, of all people that were in Canada at any time in 2007. (vii) G is a list of all weights, to the nearest kilogram, that at least one person in Canada had in 2007.please give me the solution of these
B not, just means any number that is in the universal set, that isn't in set B. You could look at the Venn diagram, and any number that is not inside of the circle labeled B would not be in B.
The 10 in the corner is a number that is in the universal set, but not in set A or B. I am not sure if that is the number you were referencing. The u in the upper right corner denotes the universal set.
You would need a 3rd circle. I don't have a video that show this exact scenario, but since you want it not in A and where C intersects B, you would set up the Venn Diagram this way: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S8RAHeD1f1g.html .The part where just B&C intersect would be your answer.
(A U B) means A or B. Let's say A={2, 4, 7, 9} and B={3, 4, 7, 10}, then (A U B) = {2,3,4,7,9,10}. To find n(A U B) just count the number of elements, so n(A U B)=6 since there are 6 elements in the union.
