Take a simple random sample from a box of 100000 tickets, the box contains 50% 0's and 50% 1's. If you draw 2500 and 25000 tickets respectively without replacement, using R studio, do 10000 replications for each part, and find the SD of all the sample percent. Moreover, make a histogram of the 10000 sample percent for each part (2 histograms).

An urn contains one yellow ball and one red ball. A ball is drawn at random; if it is yellow, no more ball is drawn. If it is red, then the ball is returned to the urn together with an extra red ball. The procedure is repeated until 4 draws have been made or a yellow ball is drawn; whichever is sooner. Let X be the number of draws. What is E(X)? The answer is 2.083. Can someone please explain...

A box contains "r" red balls, "w" white balls, and "b" blue balls. Suppose that balls are drawn from the box one at a time, at random, without replacement. What is the probability that all "r" red balls will be obtained before any white balls are obtained? The answer is (r!)(w!)/(r+w)! Can anyone explain why please?
