Likelihoods that eliminate nuisance parametersIn many cases, the likelihood is a function of more than one parameter but interest focuses on the estimation of only one, or at most a few of them, with the others being considered as nuisance parameters. Several alt… See more
Products of likelihoodsThe likelihood, given two or more independent events, is the product of the likelihoods of each of the individual events: This follows from the definition of independence in probability: the probabilitie… See more

- The likelihood of something not happening is the same subtracting the probability of that outcome from 1.0 (or 100%). For example, the likelihood of picking the black marble after taking out three other marbles would have been 1 out of 5, or 0.2.www.ck12.org/probability/applications-of-probability/lesson/Understanding-Likeli…
Probability - Math is Fun
Example: the chances of rolling a "4" with a die. Number of ways it can happen: 1 (there is only 1 face with a "4" on it) Total number of outcomes: 6 (there are 6 faces altogether) So the probability = 1 6
