P( ball drawn from second box is red)
= P( ball drawn from second box is red | 3 red balls have drawn from first box) * P(3 red balls have drawn from first box) + P( ball drawn from second box is red | 2 red balls have drawn from first box) * P(2 red balls have drawn from first box) + P( ball drawn from second box is red | 1 red ball has drawn from first box) * P(1 red ball has drawn from first box)
please so detailed steps 4. In a box are 3 red balls and 5 blue balls....
Did something strange occur? 4. In a box are 4 red balls and 7 blue balls. From this box are drawn 4 balls and placed in a second box. Then, one ball is drawn from the second box. What is the probability the ball drawn from the second box is red?
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.
please show detailed steps 5. Using the same scenario as in the problem above, if we are given the ball drawn from the second box is red, what is the probability that 2 red and 2 blue balls were transferred from box 1 to box 2?
Please ignore the section discussing the 3 diagrams. Tree Diagrams and Probability A box contains 4 red and 8 blue balls. Three balls are drawn from the box. Print the 3 different tree diagrams. 1. Complete the symbolic tree diagram by placing appropriate symbols on the branches and at the ends of the branches as indicated 2. Assuming the balls are drawn without replacement, complete the WO R diagram by placing appropriate probabilities on the branches and at the ends...
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
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?
A bowl contains 5 blue balls, 3 red balls and 2 green balls. If two balls are drawn successively at random without replacement, what is the probability of: (a) drawing a red ball on each of the two draws? (b) drawing a red ball on the second draw? (c) drawing a red ball on at least one of the two draws? (d) red on the first draw and blue on the second draw? (e) blue on the first draw given...
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
6. There are 5 red balls and 7 blue balls in an urn. Two balls are drawn consecutively without replacement. What is the probability that the first ball drawn is red given that the second ball drawn is also red?
In a box there are 6 red and 4 blue balls. By chance, one balli s taken out. If the balli s red, it is put aside. If the balli s blue, it is returned into the box. What is the probability that the second ball taken will be blue?
