What is the probability that the ball taken from B is red?
What are the global results? You know that ball transferred from A to B is red with 4/11 probability.
What is the probability of getting a red and white ball?
Therefore the probability of getting a red ball or a white ball is 4/5.
What is the probability of drawing 3 white balls?
The sample space for drawing 3 balls is {WWW,BBB,RRR,WBB,WRR,RBB,RWW,BRR,BWW}. So required probability is 1/9. But answer given is 1/56.
What is the probability that the ball is red or white?
What is the probability that is red?
In a deck of cards, there are 6 red-faced cards. So, the probability of drawing a red-faced card is 6 out of 52 cards.
What is the probability of getting 2 white balls?
Number of ways of picking up a second white ball are 4/7. Thus probability of picking up 2 white balls P(WW) = 5/8 * 4/7 = 20/56.
How many balls can be drawn from a bag?
A bag contains 2 white balls, 3 black balls and 4 red balls. In how many ways can 3 balls be drawn from the bag, if at least one black ball is to be included in the draw 64 128 132
How many red balls are in a bag of balls?
Ex15.1, 8 A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is (i) red?
How many white and black balls are there in bag B?
Bag A Contains 2 white and 3 black balls, Bag B Contains 5 white and 7 black balls. Ball is selected at random and is black. Bag A Contains 2 white and 3 black balls, Bag B Contains 5 white and 7 black balls. Ball is selected at random and is black.
What is the difference between bag 2 and BAG 3?
Bag II contains Bag I contains 1 white, 2 black and 3 red balls; Bag II contains 2 white, 1 black and 1 red balls; Bag III contains 4 white, 3 black and 2 red balls. A bag is chosen at random and two balls are drawn from it with replacement.
