You might hate this question, but you need a game plan for how to answer it. “You need to demonstrate self-awareness with the ability to address your weakness,” Buffett said. “That approach ...
Graphs of probabilities of getting the best candidate (red circles) from n applications, and k/n (blue crosses) where k is the sample size. The secretary problem demonstrates a scenario involving optimal stopping theory [1] [2] that is studied extensively in the fields of applied probability, statistics, and decision theory.
What is the probability of winning the car by switching given the player has picked door 1 and the host has opened door 3? The answer to the first question is 2 / 3 , as is shown correctly by the "simple" solutions. But the answer to the second question is now different: the conditional probability the car is behind door 1 or door 2 ...

[ 16 ] Online surveys can be tailored to the situation (e.g., respondents may be allowed save a partially completed form, the questionnaire may be preloaded ...
Because selection is performed on the individual level, families with two or more affected children would have a higher probability of becoming included in the study. Complete truncate selection is a special case where each family with an affected child has an equal chance of being selected for the study.
