Q1: Give a bijective proof of the following identity E (%) = 2:1 using the following steps: (a) Use binomial paths represented as sequences (or tuples) of steps to define a set 24 representing the left-hand side. (b) Define a set Nr representing the right-hand side as a certain set of tuples with entries from the set {0,1}. (c) Define a bijective function I : 124 + S2R. (d) Show that your function in (c) is well defined. (There is...
Question 8 Let R be relation on a set A. 1. When is R said to be an equivalence relation? Give a precise definition, using appropriate quantifiers etc. 2. When is R said to be an partial order? Give a precise definition, using appropriate quantifiers etc (You don't need to redefine things that you defined in the previous part... you may simply mention them to save time.) 3. On Z, define a relation: a D biff a - b is...

please do question 4. Note that we follow the convention of denoting the set of attributes {A, B, C} by ABC when we write FDs but not when we write schemas. Given the following set set F of FDs on schema R= (A, B, C, D, E,G): A + BC AB + CD B +C E →D G +C EG → AD Answer the following questions. Questions 1-4 require a formal proof or disproof. A proof may be given either...
