Suppose that we have a box containing 3 red balls and 4 blue balls, if two balls are selected randomly from the box in succession without replacing the first, what is the probability that both balls are in the same color ?

(+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 that two balls are drawn in succession from a bag containing 5 red balls, 4 green balls, and 3 blue balls with the assumption that the first ball is replaced befire a second one is drawn. How many ways will be drawing both red or both blue ?
3. (9 points) A box contains three blue balls and two red balls. Two balls are randomly drawn from the box one after another without replacement. Determine the probability that (a) two drawn balls are both red. (b) one ball is red and one ball is blue. (c) at least one of two drawn balls is blue.
Suppose that there is a white urn containing two white balls and three red balls and there is a red urn containing three white balls and four red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red. The probability of the second ball being...
Part B 5* 7. 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? ) both end balls are blue ?
3. A box contains 10 red balls, 6 blue balls, and 4 white balls. We have taken 2 balls from the box. What are probabilities that we have taken c) one red ball and one white ball b) at least one blue bal a) 2 blue balls d) no one red ball
box 1 3 blue and 2 ref balls. box 2 has 1 blue and 4 red balls. a box is selected randomly and a ball is drawn. what is the probability that now box2 has no blue ball
6. A box contains 30 red balls, 30 white balls, and 30 blue balls. If 10 balls are selected at random, without replace- ment, what is the probability that at least one color will be missing from the selection? 6. A box contains 30 red balls, 30 white balls, and 30 blue balls. If 10 balls are selected at random, without replace- ment, what is the probability that at least one color will be missing from the selection?
There are 4 red balls, 5 green balls, and 6 blue balls inside a box. a. If one balls is selected at random, what is the probability that the ball is green color? b. If one ball is selected at random, what is the probability that the ball is not red?
Consider an urn containing 6 red balls and 3 blue balls from which 3 balls are selected without replacement. What is the probability of selecting a red ball, if you select exactly one blue ball?
