Probability with and without replacement
Webb6 okt. 2024 · Say you had numbers 1,2 and 3 and you wanted to calculate the number of ways you could pick 2 of these numbers without replacement. Then, you could pick 3 numbers on the first trial and 2 numbers on the second trial so the total ways of picking two numbers without replacement is 3 * 2 = 6. But this is (3 choose 1) * ( 2 choose 1 ). http://www.shodor.org/interactivate/lessons/ReplacementProb/

WebbSampling with probability proportional to size is usually done with replacement, for if it is done without replacement, the probability ceases to be strictly proportional to size, unless some special device is used, such as that proposed by Yates and Grundy, which is rather complicated for n = 2 and hardly practicable for n > 2.

The probability 1 is chosen first is 1 / 9. Given that 1 was chosen first, the probability 7 is chosen third is 1 / 8, for a probability of 1 / 72. Remark: In the without replacement part, all permutations are equally likely. paint planet earth
