  • Hypergeometric distribution

    serch.it?q=Hypergeometric-distribution

    In probability theory and statistics, the hypergeometric distribution is a discrete probability distribution that describes the probability of successes (random draws for which the object drawn has a specified feature) in draws, without replacement, from a finite population of size that contains exactly objects with that feature, wherein each draw is either a success or a failure. In contrast, the binomial distribution describes the probability of successes in draws with replacement. In statistics, the hypergeometric test uses the hypergeometric distribution to calculate the statistical significance of having drawn a specific successes (out of total draws) from the aforementioned population. The test is often used to identify which sub-populations are over- or under-represented in a sample. This test has a wide range of applications. For example, a marketing group could use the test to understand their customer base by testing a set of known customers for over-representation of various demographic subgroups (e.g., women, people under 30).

  • Karla Homolka

    Karla Leanne Homolka (born May 4, 1970), also known as Leanne Teale, is a Canadian serial killer who, with her first husband Paul Bernardo, raped and murdered at least three minors. She attracted worldwide media attention when she was convicted of manslaughter following a plea bargain in the 1991 and 1992 rape-murders of two Ontario teenage girls, Leslie Mahaffy and Kristen French, as well as the rape and death of her sister Tammy. Homolka and Bernardo were arrested in 1993. In 1995, Bernardo was convicted of the two teenagers' murders and received life in prison and a dangerous offender designation, the full maximum sentence allowed in Canada. During the 1993 investigation, Homolka stated to investigators that Bernardo had abused her and that she had been an unwilling accomplice to the murders. As a result, she struck a deal with prosecutors for a reduced prison sentence of 12 years in exchange for a guilty plea to the charge of manslaughter. Homolka scored 5/40 on the Psychopathy Checklist, in contrast to Bernardo's 35/40. However, videotapes of the crimes surfaced after the plea bargain and demonstrated that she was a more active participant than she had claimed.

    This list of Internet top-level domain (TLD) extensions contains top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet. The official list of all top-level domains is maintained by the Internet Assigned Numbers Authority (IANA) at the Root Zone Database. IANA also oversees the approval process for new proposed top-level domains. , the root domain contains 1543 top-level domains, while a few have been retired and are no longer functional.
