Yes, F and G are mutually exclusive events Since these 2 events can not occur at the same time.
No, G and H are not mutually exclusive events. Since both have common cases that is first ball is white but second ball is red.

Probability question *A box contains 3 white balls, 4 black balls, and 3 red balls. Consider selecting 3 balls at random. (a) What is the probability that you pick exactly one of each color when you select 3 balls from the box? (b) What is the probability that you pick exactly 2 white balls and 1 red ball? (c) What is the probability that at least one of the balls is white when you select 3 balls from the box?

There are 10 balls in a box. 2 of them are red and the other 8 are white. John draws one ball randomly from the box. Then Emily draw another ball randomly from the remaining 9 balls. Let E be the event that John draws a red ball. Let F be the event that Emily draws a red ball. (i) Write out P(E), P(F|E), P(F|EC) directly. (ii) Find out P(F). (Hint: Apply the law of total probability) Suppose that they...
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.
There are 3 white, 3 red and 5 black balls in a box. By chance, three balls are taken out from the box. The person wins 1 dollar when taking out a white ball but loses 1 dollar when taking out a red ball. X is an event, describing the amount of money that was won (lost) in one try. What values does X have and what are the probabilities of those values? What is the probability that the money...
Problem 1 A box has eight balls. There are four green balls and four yellow. The four green balls are numbered 1,2,3, and 4. The four yellow balls are numbered 1,2,3, and 4. The box is shaken. One ball is selected will mean that a green Answer the following questions, using fractions in p/q format or decimal values accurate to the nearest 0.01 .Here G ball is selected, Y that a yellow ball is selected, and E that an even-numbered...
Michael has a box of colored balls. It contains two red balls, two green balls, two yellow balls, and five blue balls. Michael draws a ball at random from the box Let R denote the event that the ball he draws is red, and let B denote the event that the ball he draws is blue. What is Pr(R|B)? What is Pr(R|B′)? Enter your answers as whole numbers or fractions in lowest terms. A bag contains four 1-dollar bills, three...
This question is about the Bayes' Theorem. You are given two boxes. Box 1 contains 5 red, 5 green, and 3 blue balls, and Box 2 contains 4 red, 3 green, and 2 yellow balls. You are asked to randomly pick one of the two boxes. Holding that box, you grab one ball at random, and then set the box back down. You found out that it is a red ball. Let A be the event that you choose Box...
3. Suppose that there are three balls in a box. Each ball is either red or white. Let o be the number of red balls in the box. Then 0 € {0,1,2,3}. Suppose that we'd like to test Ho : 0 = 0 against H:8 > 0. To this end, randomly draw a ball from the box. Define ſi, a red ball is drawn 10. a white ball is drawn Then P(Y = 1) = 0/3. Suppose that we reject...
Question 29 (4 points) Two boxes each contain five numbered balls: • Box 1 contains balls with numbers 3, 3, 3, 4, 5 • Box 2 contains balls with numbers 1, 1, 2, 2, 2 (a) You will randomly select one ball from each box. Let X be the difference between the numbers selected from the first and second box. Find the probability distribution of X. You can simply list the probabilities for each possible value of X instead of...
