[2] The first Advanced Placement exams were administered in 1954 by the Educational Testing Service (ETS) to students limited to 27 schools participating at that time. In 1955, the College Board assumed leadership of the program and testing, deciding on curricula and pedagogical approaches, while retaining ETS to design and score the tests.
The multiple choice section is scored by computer, with a correct answer receiving 1 point, with omitted and incorrect answers not affecting the raw score. This total is multiplied by 1.2 to calculate the adjusted multiple-choice score. [26] The free response section is hand-graded by hundreds of AP teachers and professors each June. [27]

For example, if a = 2 and p = 7, then 2 7 = 128, and 128 − 2 = 126 = 7 × 18 is an integer multiple of 7. If a is not divisible by p, that is, if a is coprime to p, then Fermat's little theorem is equivalent to the statement that a p − 1 − 1 is an integer multiple of p, or in symbols: [1] [2] ().
[41] [42] For instance, the certainty of the Higgs boson particle's existence was based on the 5σ criterion, which corresponds to a p-value of about 1 in 3.5 million. [ 42 ] [ 43 ] In other fields of scientific research such as genome-wide association studies , significance levels as low as 5 × 10 −8 are not uncommon [ 44 ] [ 45 ] —as the ...
For example, for A the first of these cells gives the sum of the probabilities for A being red, regardless of which possibility for B in the column above the cell occurs, as 2 / 3 . Thus the marginal probability distribution for A {\displaystyle A} gives A {\displaystyle A} 's probabilities unconditional on B {\displaystyle B} , in a ...
Since F is uniformly bounded, the set of points {f(x 1)} f∈F is bounded, and hence by the Bolzano–Weierstrass theorem, there is a sequence {f n 1} of distinct functions in F such that {f n 1 (x 1)} converges. Repeating the same argument for the sequence of points {f n 1 (x 2)} , there is a subsequence {f n 2} of {f n 1} such that {f n 2 (x ...
