Consider a population with m+n elements, where n of them are 1 and m of them are 0. Then sample two points randomly from the population.

a) Suppose we sample them without replacement, which corresponds to the random sample. Calculate the probability of the outcomes (0,0), (0,1), (1,0) and (1,1).

b) Suppose we sample them with replacement. Calculate the probability of the outcomes (0,0), (0,1), (1,0) and (1,1).

Consider 5 fish in a bowl: 3 of them are red, and 1 is green, and 1 is blue. Select the fish one at a time, without replacement, until the bowl is empty. Let X=1 if all of the red fish are selected, before the green fish is selected; and X=0 otherwise. Let Y=1 if all of the red fish are selected, before the blue fish is selected; and Y=0 otherwise. a. Find the joint probability mass function of X...

If we sample from a small finite population without? replacement, the binomial distribution should not be used because the events are not independent. If sampling is done without replacement and the outcomes belong to one of two? types, we can use the hypergeometric distribution. If a population has A objects of one? type, while the remaining B objects are of the other? type, and if n objects are sampled without? replacement, then the probability of getting x objects of type...
