There are black, blue, and white marbles in a bag. The probability of choosing a black marble is 0.36. The probability of choosing a black and then a white marble is 0.27. To the nearest hundredth, what is the probability of the second marble being white if the first marble chosen is black?
Suppose there is an urn containing 5 red, 4 white, and 11 blue balls. We drawn six balls from the urn (no replacement) (a) Find the number of ways (not the probability) of choosing a red ball, then a blue ball, then exactly 2 white balls, and finally exactly 2 blue balls. (b)Find the number of ways of choosing 2 red balls initially , then at least 3 blue balls, then a green ball. (c) Find the number of ways...
3. I have a box with 4 blue chips and 6 white chips. I randomly pull a chip from box 1and put it in box 2 which contains 3 blue chips and 8 white chips. Then I randomly pull a chip from box 2 and put it in box 3 which contains 6 blue chips and 3 white chips. a) What is the probability I pull a blue chip from box 3? b) What is the probability I pull a...

A box with 3 green marbles, 4 white marbles, 2 blue marbles, and 1 red marble is sitting on the counter. If you are blind-folded and select two marbles without replacement, what is the probability you will get: a) two blue marbles ________ b) a white marble and then a green one _________ c) a green marble and then a blue one _______ d) two red marbles __________ e) no blue marble ________ f) at least one blue marble _________
(+5)* 6. Suppose that a box contains 2 red balls, 3 white balls, and 4 blue balls. Suppose also that balls are selected from the box one at a time, at random, without replacement. What is the probability that a) all white balls will be obtained in a row? b) both end balls are blue?
Suppose we have 3 baskets, the first containing 6 white and 4 blue balls, the second containing 1 white and 9 blue balls, and the third containing 3 white and 7 blue balls. If a ball is selected from one of the baskets, (each of the balls being equally likely), and the ball is white, what is the probability that it came from the second basket?
An urn “A' contains 2 white and 4 black balls. Another urn ®contains 5 white and 7 black ball. A ball is transferred from the urn $A)to urn B'. Then a ball is drawn from urn B'. Find the probability, thatit will be white.
A bag contains 4 white, 5 red and 6 blue balls. Three balls are randomly drawn, without replacement, from the bag. What is the probability that the first two balls are red and the last one is blue?
