The sample space for the second event is then 19 marbles instead of 20 marbles. Observe: Dependent Probability (“without replacement”) Starter In this question you will need to draw two tree diagrams and answer the same questions twice — once for ‘with replacement’ and once for ‘without replacement’. 06 or 6% 5) The probability of picking a red ball is 4/10 and the probability of picking a green ball is 3/10 and because the ball is put back in the box, the second green is also 3/10. Foster and Sergiu Hart View PDF HTML (experimental) Abstract: We provide bounds on the tail probabilities for simple procedures that generate random samples _without replacement_, when the probabilities of being selected Example Problem 2: Calculating the Probability of Draws Without Replacement A bag of marbles has 10 green marbles, 20 blue marbles, and 30 red marbles.
