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 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.
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?
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)
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.
(+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?
An urn contains 7 white balls and 3 black balls. Two balls are selected at random without replacement. What is the probability :1 The first ball is black and the second ball is white.? 2: One ball is white and the other is black? 3:the two balls are white ?
A bag contains 4 white, 5 red and 6 blue balls. Three balls are randomly drawn, without replacement, from the bag. What is the probability that the first two balls are red and the last one is blue?
1. From an urn, 10 balls with replacement are selected, the urn contains 14 white balls and 5 red balls. Calculate the probability that less than 3 red balls have come out. 2. From an urn, 10 balls are selected with replacement, the urn contains 14 white balls and 14 red balls. Calculate the probability that at least 3 red balls have come out. 3. From an urn 5 balls without replacement are selected, the urn contains 11 balls, of...
