There is a box of 20 marbles. Of these marbles, 6 are red, 8 are green and 6 are blue. 6 marbles are randomly selected from the box without replacement. Let X be the number of marbles that are red or blue, and let Y be the number of marbles that are blue. a. What is the probability the first and second marbles are red, the third and fourth are blue and the fifth and sixth are green? b. What...
Question 8 A box contains 9 green marbles, 8 blue marbles, and 5 red marbles. Three marbles are selected at random from the box, one at a time, without replacement. Find the probability that the first marble is red, the second marble is green, and the third marble is blue. Round your answer to four decimal places.

A box contains 3 red and 4 green marbles. Five marbles are drawn without replacement. Let X denote the number of red marbles obtained. a) Construct the probability distribution of X. b) What is the expected number of red marbles?
A box contains 9 green marbles, 6 blue marbles, and 8 red marbles. Three marbles are selected at random from the box, one at a time, without replacement. Find the probability that the three marbles selected are all different colors.
A box contains seven marbles. Four of them are red and 3 of them are green. You reach in and choose three at random without replacement. Define a random variable X as: X = the number of red marbles selected. (a) What are the possible values X can take on? (i.e. give Im(X)) (b) Find P(X = x) for all x in Im(X). (c) Make a table for the probability distribution of X as shown in lecture. (Leave probabilities as...
Suppose an opaque jar contains 7 red marbles and 10 green marbles. The following exercise refers to the experiment of picking two marbles from the jar without replacing the first one. What is the probability of getting a green marble first and a red marble second? (Enter your probability as a fraction.) this problem is posted on your page, however, the answer is incorrect. Thank you!
You make a selection of marbles from a box that has 7 Red marbles, 8 Blue marbles and 10 Green marbles. Answer parts (a) and (b). a. Assume that the selections are made with replacement. What is the probability that you select a Red marble and then a Green marble? b. Now assume the selections are made without replacement. What is the probability that the first marble is Blue the second is Red?
