Polls and Probability Have you ever wondered how public opinion polls can provide an accurate prediction of a future event, such as the outcome of a presidential election? After all, the number of people sampled is much smaller than the population size. In fact, this approach of taking samples...
Theprobabilityof thecomplementeventA'A′isP(A')P(A′), which is equal to1−PA1-PA. P(A')=1−PAP(A′)=1-PA Substitute the value ofP(A)P(A)intoP(A')=1−PAP(A′)=1-PA. P(A')=1−(0.69)P(A′)=1-(0.69) Multiply−1-1by0.690.69. ...

A more interesting question is how the number 5050 is obtained. This is an example of a real-life problem in which tools from probability and statistics are used. As you read more chapters from the book, you will learn many of these tools that are frequently used in practice....
Although we cannot hope to model the process of forming a judicial belief in its entirely, those facets of factfinding where quantitative estimates are typically made implicitly and intuitively could benefit from the aid provided by tools such as mathematical probability theory and statistics....
It is possible to have hash collisions in which dissimilar queries and query plans have the same hash value. Although the probability of hash collisions is very small and unlikely to occur, applications that depend on the uniqueness of the query hash and query plan hash can have errors because...
