There are 7 balls in a bag. They are identical except for color. 3 are red, 2 are white and 2 are blue. You are to draw 1 ball from the bag, note its color, and set it aside. Then you are to draw a second ball from the bag and note its color.

a. Make a tree diagram to show all possible outcomes of the experiment. Label the probability associated with each stage of the experiment on the appropriate branch.

b. Compute the probability for each outcome of the experiment.

Given that -

There are 7 balls in a bag. They are identical except for color. 3 are red, 2 are white and 2 are blue. You are to draw 1 ball from the bag, note its color, and set it aside. Then you are to draw a second ball from the bag and note its color.

a) tree diagram is -

b) Let P(x, y) be the probability of choosing an x-colored ball on the first draw and a y-colored ball on the second draw. Compute the probability for each outcome of the experiment.

Bag 1 contains 3 red balls and 7 green balls. Bag 2 contains 8 red balls and 4 green balls. Bag 3 contains 5 red balls and 11 green balls. Bag 1 is chosen twice as often as either Bag 2 or Bag 3 (which have the same probability of being chosen). After a bag is chosen, a ball is chosen at random from that bag. Calculate the probability that: a) a red ball is chosen b) a red ball...

There are 10 marbles in a jar. They are identical except for color. Four are Red, three are Blue, two are Yellow and one is White. You draw a marble from the jar, note its color, and set it aside. Then, you draw another marble from the jar and note its color. a) What is the probability that you draw two Red marbles? b) What is the probability that you draw a Blue marble GIVEN that you have drawn a...

There are 10 identical red balls, 10 identical blue balls, 10 identical green balls and 2 distinct boxes. How many ways to place all the 30 balls in the two boxes such that each box contains 15 balls?

A bag has 3 red balls and x white balls. A random ball is dragged out...

A bag has 3 red balls and x white balls. A random ball is dragged out from the bag and replaced with a ball of the other color. If a second ball is dragged knowing that the probability that this second ball is red is 17/50, then find the number of white balls.

A bag contains 4 red balls and 8 green balls. (a). (5’) Three balls are selected from the bag randomly. What is the probability that 1 red ball and 2 green balls are selected? (b). (10’) Three balls are selected from the bag sequentially without replacement, and the first ball is discarded without observing the color. If the third ball is green, what is the probability that the second ball is red? (c). (10’) Two balls are selected from the...

there is a bag containing 2 red balls, 2 blue balls, 2 brown balls, and 2 green balls. A subset of 4 balls are randomly drawn. Consider that X is the number of colors drawn in this subset, what is E(X)?

A bag contains 8 red balls and some white balls. If the probability of drawing a white ball is half of the probability of drawing a red ball then find the number of white balls in the bag.

Consider an urn containing 3 red balls, 5 yellow balls, 7 blue balls, and 6 violet balls. If 4 balls are drawn at random, what is the probability of drawing one of each color? Suppose we draw 8 balls from the urn above. What is the conditional probability that 4 of them are blue with respect to the event that none of them are yellow?

A bag contains 4 Blue, 5 red and 3 green balls. Debolina is asked to pick up three balls at random, one by one without replacement from that bag. If the balls picked up are of same colour then Debolina will get Rs. 7000, if the balls picked up are of different colour, then she will get Rs. 9000, but otherwise she has to pay Rs. 4000. a) Find the expected gain of Debolina if she plays the game. b)...
