1. Consider the sets: A = {a, b, c, d, e, f, h, j}, B = {a, b, i }, C = {f, h} and U = {a,b,c,d,e,f,g, h,i,j} a. Draw a Venn diagram and place each element in its appropriate region. Insert a photo of your diagram into your HW document. b. Is C a subset of A? Why? C. Is C a subset of B? Why? d. Is A a subset of B? Why? e. Are B and...
Consider sets A, B, and C where \(A \cap B \neq \emptyset\) and \(A \cap C \neq \emptyset\) and \(B \cap C \neq \emptyset\). Consider the following set expression:$$ \overline{((A \cup B)-(A \cap B)) \cup((B \cup C)-(B \cap C)) \cup((A \cup C)-(A \cap C))} $$a) Draw an appropriate Venn diagram and shade the area represented by the set expression above.b) Write the dual of the set expression above.c) Are the sets \(A \cap B, A \cap C\), and \(B \cap C\)...

(d) If A and B are two boxes (possibly with things inside), describe the following in terms of boxes A B, P(A), and A.
Consider the following venn diagram with universal set, U, and sets A and B. The numbers in the diagram give the COUNTS of elements in the region. Assume we know that: n(U)=196 Consider the following venn diagram with universal set, U, and sets A and B. The numbers in the diagram give the COUNTS of elements in the region. Assume we know that: n(U) 196 Ul 37 79 69 Find each of the following: ROUND TO THREE DECIMAL PLACES! P(A)-...
Let X be a set and let T be the family of subsets U of X such that X\U (the complement of U) is at most countable, together with the empty set. a) Prove that T is a topology for X. b) Describe the convergent sequences in X with respect to this topology. Prove that if X is uncountable, then there is a subset S of X whose closure contains points that are not limits of the sequences in S....

The survey showed that 180 learned about the sale from the radio, 170 from television, 130 from the newspaper, 120 from radio and television, 70 from radio and newspapers, 80 from television and newspapers, and 60 from all three sources. How many people...
