An urn contains 39 red, 17 white and 30 blue marbles. A child selects two marbles at random and without replacement from the urn. Find the probability that the colors of the selected marbles are different. Hint: Three cases occur in the selection: no red, no white, no blue.
An urn contains 21 red marbles, 19 blue marbles, and 40 yellow marbles. One marble is to be chosen from the urn without looking. What is the probability of choosing a red or a blue marble? Your answer should be rounded to 4 decimal places.
An urn contains three red marbles and five blue marbles. A marble is picked at random and is not replaced. A second marble is then picked from the urn. Determine the following: (a) P(both marbles are red) (b) P(both marbles are blue) (c)P(both marbles are the same color)
An urn contains 8 red marbles, 6 white marbles and 7 blue marbles. A child randomly selects three (without replacement) Find the probability all have the same color. Hint: Three distinct cases occur for the same color. Preview Find the probability that none is white. Preview

An urn contains 15 different colored marbles, 7 are red, 5 are blue, and 3 are green. Part 1. If two balls are randomly picked from the urn without replacement a) b) Determine the sample space What is the probability of grabbing a red marble on the first pick and then a green marble on the second pick? Did you use the classical or empirical approach to calculate the probability in part b? Are these events independent or dependent? Disjoint...

Sarah, Sally, and Sandra take their turn drawing two marbles each, one at a time, and without replacement. a. if sarah is the first to draw two marbles, what is the probability she draws two blue marbles? b. if sarah is the last to draw two marbles, what is the probability she draws two blue marbles. c. if sandra is the last...
An urn contains a total of 5 marbles: ese are 1 red, 1 yellow, and 3 green. Two marbles will be drawn from the urn at random, one at a time, without replacement. Define the following events: Ri: the event that the first draw will be red. G2: the event that the second draw will be green. R2: the event that the second draw will red. a) (1 pt each) Find P(RI)- P(G2)- b) (2 pts) Find c) (2 pts)...
