use venn diagrams to show AuB' is equal to A'nB'
A = 1 & 2
B = 2 & 3
outlaying area = 4
2.2. Use Venn diagrams to verify the two De Morgan laws: (b) (AUB) A'n B'.
1. Let A, B and C be events in the sample space S. Use Venn Diagrams to shade the areas representing the following events (32 points) a. AU (ANB) b. (ANB) U ( AB) C. AU ( ANB) d. (AUB) N (AUC)
4. On the following Venn diagrams, use shaded area to represent (a) (An B')UC (b) (A -B)nc. (c) (BUC)n(A'UB). B S
3. (12') Using Venn diagrams, verify the following identities. (a) A-(AnB)U(A-B) ( b) If A and B are finite sets, we have (AUB)- A+B-(AnB )
3 4 . Find the simplest expression for the following event (Venn diagram can help): (AUB)(AUB)(AUB)
5. If possible, draw Venn Diagrams illustrating the following conditions: (a) (A B) = (Cr) B), and A C. (b) (A u B) (C u B), and A = C. 6.-7. Prove or disprove using Truth Tables that 8. Let X = { a, b, c }, Ys { 2, 3 }. List the elements of (a) Y x X (b) Yx Xx Y 9-12. Given the following formula, shade in the area of the Venn diagram that it represents....
2.4. Use Venn diagrams to verify that if A is contained in B, then AnB A and AnB'.
False Question 3 (1 point) <Venn 5> There are 2 events: A, B with P(A)-0.5, P(B)-0.4, P(AUB)-0.7 Find P(A n B) Question 4 (1 point) Saved <Venn 2 There are 2 events: A, B with P(A)-Q5, P(B)-0.4, PAUB)-0.7
1. Show that if A and B are countable sets, then AUB is countable. 2. Show that if An are finite sets indexed by positive integers, then Un An is countable. 3. Show that if A and B are countable sets, then A x B is countable. 4. Show that any open set in R is a countable union of open intervals. 5. Show that any function on R can have at most countable many local maximals. Us
Use membership tables (i.e., no set identities or Venn diagrams)
to demonstrate that
4. Use membership tables (i.e., no set identities or Venn diagrams) to demonstrate that ((Y U Z) n (X UZ)) – (Y nz) and (2 U(Y nx)) ((CY NZ) ux)u((YnZ)n x)) are equivalent expressions. (5 marks)
