Two bags contain a number of balls. Bag A contains 4 white and 3 black balls and bag B contains 3 whit and 5 black balls. A ball is chosen at random from bag A and placed into bag B i). Given that the first ball was black, what is the probability that a second ball drawn from bag A will be white? (1 mark) Given no knowledge of the color of the first ball, what is the probability that...
A bag contains 6 blue balls, 2 red balls and 1 black ball. If two are selected at random, find the probability of obtaining the black ball.
A bag contains 6 black balls,5 red balls and 4 white balls,if 3 are selected at random without replacement determine the probability that (1)all 3 are black (2)all 3 are red (3)2 are black and 1 white (4)at least 1 of each colour is selected.
one bag contains 4 white balls and 3 black balls, and a second bag contains 3 white balls and 5 black balls . we first toss a fair coin .if it is head , one ball is drawn from the first bag and placed in the second bag.if it is a tail , one ball is drawn from the second bag and placed in the first bag.let the event A be that a ball is now drawn from the second...
One bag contains 4 white and 2 black balls. Another contains 3white and 5 black balls. One ball is drawn from each bag. Find theprobability that both are of same colour.
An urn contains 7 white, 3 red and 10 black balls. If five balls are drawn at random, find the probability that at least one red ball is selected.
this is the last problem. 6. A jar contains 5 red balls and 5 black balls. Two balls are successively drawn from the jar. After the first draw the color of the ball is noted, and then the selected ball is returned to the jar together with another ball of the opposite color. In other words, if a red ball is drawn it is returned to the jar together with another black ball; if black ball is drawn it is...
If a bag contains: 5 White Balls, 6 Red Balls, and 9 Black Balls, what is the probability of pulling out: a. A black or white ball b. A white ball c. A white ball and then a black ball without replacement? d. A white ball and then a black ball with replacement?
Bag A contains two balls, one red and one white and Bag B contains two white balls. A bag is selected at random, and one ball is taken at random from that bag. If the selected ball is white, what is the probability that the other ball in the bag is red? Give your answer as a fraction in its simplest form.
Q10. A bag contains 4 white, 5 red and 6 blue balls. Consecutively 2 balls are drawn at random from the bag. The probability that all of them are red, is what? Calculate the provability for both with replacement and non-replacement.
