Ranked Pairs (RP), also known as the Tideman method, is a tournament-style system of ranked voting first proposed by Nicolaus Tideman in 1987. [ 1 ] [ 2 ] If there is a candidate who is preferred over the other candidates, when compared in turn with each of the others, the ranked-pairs procedure guarantees that candidate will win.
Note 1: Using American Contract Bridge League (ACBL) methods, scoring is one point for each pair beaten, and one-half point for each pair tied. Note 2: The rule of two matchpoints for each pair beaten is easy to apply in practice: if the board is played n times, the top result achieves 2n−2 matchpoints, the next 2n−4, down to zero. When ...
For example, the "primitive" friendly pair 6 and 28 gives rise to friendly pairs 6n and 28n for all n that are congruent to 1, 5, 11, 13, 17, 19, 23, 25, 29, 31, 37, or 41 modulo 42. [4] This shows that the natural density of the friendly numbers (if it exists) is positive.
Example Condorcet method voting ballot. Blank votes are equivalent to ranking that candidate last. A Condorcet method (English: / k ɒ n d ɔːr ˈ s eɪ /; French: [kɔ̃dɔʁsɛ]) is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, whenever there is such a candidate.

42 is the name of the private computer science school with campuses located in Paris, France, and Fremont, California. 42 is the sum of the numbers on a pair of dice. There are 42 eyes visible on face cards in a standard deck of playing cards. 42 (dominoes) is a trick-taking game played with dominoes, rather than cards. Originated and ...
Registers were increased to 8 for memory, 1 for formula (44 characters), and can store up to 3 list formulas (up to 42 characters or items). Physical constants are increased by 4 to 20, conversion sets are increased to 40 (20 pairs). Binary mode is restored for Base calculation. Other new functions over TI-36X II include:
To see this, first note that there are 2 n ordered pairs of complementary subsets A and B. In one case, A is empty, and in another B is empty, so 2 n − 2 ordered pairs of subsets remain. Finally, since we want unordered pairs rather than ordered pairs we divide this last number by 2, giving the result above.
