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...
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.
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 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.
asic Statistics Bag 1 contains 5 red balls and 3 black balls. Bag 2 contains a red balls and 1 black ball. Bag 3 contains 4 red balls and 2 black balls. If a bag is selected at random and a ball is drawn, find the probability it will be red (5 marks)
Urn "A" contains 5 white balls and 4 black balls, whereas urn B contains 3 white balls and 5 black balls. A ball is drawn at random from urn "B" and placed in urn "A". A ball is then drawn from urn "A". It happens to be black. What is the probability that the ball transferred was black?
A bag contains 4 white and 3 black balls. Four players (A,B,C, and D) agree to take turns drawing balls from this bag(without replacement) until a white ball is drawn. If the first player (A) draws a white ball, he gets $56. If he draws a black ball, he must pay $28 into the pot. the game continues until a white ball is drawn. Find the expected value to each of the 4 players, assuming each player initially pays in...

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?
3. There are 6 balls in a bag with 2 being white and 4 black. If one draws 18 balls from the bag with replacement, let y be the number of black balls drawn. • Identify the name of the probability distribution of Y. Find its expected value and variance • Use Tchebysheff's inequality to estimate an upper bound of the probability that Y 38 or Y 2 16.
