A bag has 100 red balls and 100 blue balls. Each time you pick one out with no replacement. You stop when the colors of the balls left in the bag are the same. What is the expectation of the number of balls left in the bag (eventually)?

There are 100 balls of the same shape and same weight in one bag. The balls' colors are different: 30 red balls, 20 yellow balls, 22 blue balls and 28 white balls. You are blindfolded and asked to draw three balls from the bag without replacement. Calculate the probability that there is exactly one red ball among the three balls.
A bag contains 3 red and 1 orange ball. You pick two balls from the bag with replacement. What is the probability that you will get two orange balls?
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) Suppose a bag contains 50 red balls, 30 green balls and 20 blue balls. (a) If you draw 2 balls at random without replacement, what is the probability that they are red and green? (b) If you draw 3 balls at random without replacement, what is the probability that all 3 are of different colour? (c) If you draw 3 balls at random without replacement, what is the probability that you draw at least 1 red ball? 2) A...
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.
There are 1 0 balls in a bag, 4 red balls, 2 black balls, and 4 yellow balls. Every time you can pick one ball without replacement. Now you pick 2 times. (1) How likely you will have 2 black ball ls if you pick 2 times. (2) How likely you will have one red ball and one yellow ball if you pick 2 times. (3) How likely you will have at least one yellow balls. Can someone explain it...
A bag contains a large number of red, green, and blue balls. Ten balls are randomly drawn from the bag, without regard to order. How many different color combinations can be drawn from the bag? Example: one combination is 1 red, 3 green, and 6 blue balls.
An urn contains three blue, four white, and five red balls. You take three balls out of the urn without replacement. What is the probability that all three balls are of the same color? The probability is (Type an integer or a simplified fraction.)
There are two boxes with red and blue balls in them. Box I has 1 red and 4 blue balls; Box II has 3 red and 2 blue balls. There is a fair coin with Box I written on one side and Box II written on the other. You toss the coin and then draw 2 balls without replacement out of the box that comes up on the face of the coin. a. Let Y be the number of red...
