Prove or disprove the following proposed inference rules for functional dependencies.
A proof should be made by using the reflexive, augmentation, transitive, decomposition, union, and pseudotransitive rules.
A disproof should be performed by demonstrating a relation instance that satisfies the conditions and functional dependencies on the left hand side of the proposed rule but does not satisfy the dependencies on the right hand side.
No other form of dispoof will be accepted.

In this problem, we consider a very restricted subset of Boolean expressions. Define an operator to be one of the four symbols: ¬, ∧, ∨, and →. Define a variable to be one of the five symbols
For a binomial distribution with n = 100, explain how to determine the smallest and largest values of p that pass the rule-of-thumb test.
Show that the language F = {a^i b^j c^k | i, j, k greater than or equal to 0 and if i = 1 then j = k} is not regular. Show, however, that it satisfies the statement of the pumping lemma
Non-terminal A is useless if there is no derivation from start symbol to string of tokens in which A appears. Write a mathematical formulation of this property.
It is possible to have negative weights in a weighted code for the decimal digits, e.g.,8,4, -2, and -1 can be used. Construct a table for this weighted code. Ifd is a decimal digit in this code, how can the code for 9 -d be obtained?
