In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more than t boxes need to be bought ...
Given n coupons, how many coupons do you expect you need to draw with replacement before having drawn each coupon at least once. —Preceding unsigned comment added by 131.155.59.211 11:30, 21 January 2010 (UTC) I agree with this. The problem defn. on the page was not clear to me at all. Magicmike 19:42, 22 February 2011 (UTC)
Buy one, get one free. " Buy one, get one free " or " two for the price of one " is a common form of sales promotion. Economist Alex Tabarrok has argued that the success of this promotion lies in the fact that consumers value the first unit significantly more than the second one. So compared to a seemingly equivalent "Half price off" promotion ...
The violet is the mutual information . In information theory, the conditional entropy quantifies the amount of information needed to describe the outcome of a random variable given that the value of another random variable is known. Here, information is measured in shannons, nats, or hartleys. The entropy of conditioned on is written as .
Conditional expectation. In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value evaluated with respect to the conditional probability distribution. If the random variable can take on only a finite number of values, the "conditions" are that the variable can ...
Conditional variance. In probability theory and statistics, a conditional variance is the variance of a random variable given the value (s) of one or more other variables. Particularly in econometrics, the conditional variance is also known as the scedastic function or skedastic function. [ 1] Conditional variances are important parts of ...
Conditional probability distribution. In probability theory and statistics, the conditional probability distribution is a probability distribution that describes the probability of an outcome given the occurrence of a particular event. Given two jointly distributed random variables and , the conditional probability distribution of given is the ...
Amazon will also hold “Coupon Parties,” which are limited time deals like save 20% when you buy $50 worth of Amazon brands. You can usually find these parties at the top of the Amazon coupons ...
