  2. Apportionment paradox - Wikipedia

    en.wikipedia.org/wiki/Apportionment_paradox

    In 1907, when Oklahoma became a state, it was given a fair share of seats and the total number of seats increased by that number. The House increased from 386 to 391 members. A recomputation of apportionment affected the number of seats because of other states: New York lost a seat while Maine gained one. [1]: 232–233 [2]

  3. Boole's inequality - Wikipedia

    en.wikipedia.org/wiki/Boole's_inequality

    We can use Boole's Inequality to solve this problem. By finding the complement of event "all five are good", we can change this question into another condition: P(at least one estimation is bad) = 0.05 ≤ P(A 1 is bad) + P(A 2 is bad) + P(A 3 is bad) + P(A 4 is bad) + P(A 5 is bad) One way is to make each of them equal to 0.05/5 = 0.01, that ...

  4. Checking whether a coin is fair - Wikipedia

    en.wikipedia.org/.../Checking_whether_a_coin_is_fair

    The practical problem of checking whether a coin is fair might be considered as easily solved by performing a sufficiently large number of trials, but statistics and probability theory can provide guidance on two types of question; specifically those of how many trials to undertake and of the accuracy of an estimate of the probability of ...

  6. Fair cake-cutting - Wikipedia

    en.wikipedia.org/wiki/Fair_cake-cutting

    A procedure by Aziz and Mackenzie (2016) [7] finds an envy-free division for n people in a bounded number of queries. The negative result in the general case is much weaker than in the connected case. All we know is that every algorithm for envy-free division must use at least Ω(n 2) queries. There is a large gap between this result and the ...

  7. Union (set theory) - Wikipedia

    en.wikipedia.org/wiki/Union_(set_theory)

    For example, the union of three sets A, B, and C contains all elements of A, all elements of B, and all elements of C, and nothing else. Thus, x is an element of A ∪ B ∪ C if and only if x is in at least one of A, B, and C. A finite union is the union of a finite number of sets; the phrase does not imply that the union set is a finite set ...

    In the mathematics of social science, and especially game theory, a moving-knife procedure is a type of solution to the fair division problem. The canonical example is the division of a cake using a knife .
