Exercise 1.5. Prove that if A and B are sets satisfying the property that A \ B = B \ A, then it must be the case that A = B. Exercise 1.6. Using definition (1.2.5) of the symmetric difference, prove that, for any sets A and B, A4B = (A ∪ B) \ (A ∩ B). Exercise 1.7. Verify the second assertion of Theorem 1.3.4, that for any collection of sets {Ai}i∈I, \ i∈I Ai !c = [ i∈I...
Exercise 1.8. Prove that, for any sets A and B, the set A ∪ B can be written as a disjoint union in the form A ∪ B = (A \ (A ∩ B)) ∪˙ (B \ (A ∩ B)) ∪˙ (A ∩ B). Exercise 1.9. Prove that, for any two finite sets A and B, |A ∪ B| = |A| + |B| − |A ∩ B|. This is a special case of the inclusion-exclusion principle. Exercise 1.10. Prove for...
5. In each step, explain clearly what property or axiom you are using. (a) Prove "inclusion-exclusion," that P(AUB) P(A) +P(B)-P(AnB). (b) Prove the "union bound," that P(AiUAz) < P(A) + P(A2). Under what conditions does the equality hold? (c) Prove that, for Ai and A2 disjoint, P(Ai UA2|B) P(AiB)P(A2|B) (d) A and B are independent events with nonzero probability. Prove whether or not A and B are independent.
Exercise 1.10. Prove for any set X and for any subsets A and B of X, the set A can be written as a disjoint union in the form
Exercise 1.10. Prove for any set X and for any subsets A and B of X, the set A can be written as a disjoint union in the form A = (A ∩ B) ∪ ̇ (A ∩ Bc).
It’s Statictics, please I need answer for PART 3. clear answer please. Thank you Part II Shade in the area on a Venn diagram that represents the sets lised in (a) through (h) You will have to draw a separate Venn diagram for each set For sets that involve oely two sets, A and B, start with the following Venn diagram For sets that involve three sets, A. B and C start with the following Venn diagram a AAB is...
