A history pop quiz has one question in which students are asked to arrange the following presidents in chronological order: Hayes, Taft, Polk, Taylor, Grant, and Pierce. After carefully reading the scenario, determine the number of possible different arrangements of the presidents. Which will work better to determine this answer, permutation or combination

Given six presidents to arrange in chronological order, in this case, Permutations will work better not combination.

Explanation:

In permutations, the order of the element is important. It is the arrangement of the set in a linear order. When the order of a selection is a factor, it becomes permutation.  

The first president in this list can be chosen in six different ways, like wise the second president can be chosen in five ways. There are now five presidents left, The third president in the list can be chosen in four different ways (remaining three presidents), the fifth president can also be chosen in two ways and finally the sixth president in one way.

Hence, 6.5.4.3.2.1 = 720, In the above arrangement, only one is correct, Therefore the probability is 1/720.

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
