Find the probability distribution of white balls drawn when 3 balls are drawn one by one without replacement from a bag containing 4 white and 6 red balls .

Find the probability distribution of the number of white balls drawn in a random draw of 3 balls without replacement from a bag containing 4 white and 6 red balls. Also find the mean and variance of the distribution.

An urn contains 3 white and 6 red balls. 4 balls are drawn one by one with replacement from the urn.Find the probability distribution of the number of red balls drawn. Also find mean and variance of the distribution.

A box contains 3 orange balls, 3 green and 2 blue balls. Three balls are drawn at random from the box wihout replacement. The probability of drawing 2 green balls and one blue ball is

A bag contains 5 white, 7 red and 8 black balls. If four balls are drawn one by one without replacement, what is the probability that all are white?

A bag contains 5 red and 3 blue balls. If 3 balls are drawn at random without replacement, the probability of getting exactly one red balls

A bag contains 7 red, 4 white and 5 black balls. If four balls are drawn one by one the replacement, what is the probability that none is white?

A urn contains 4 white and 6 red balls. Four balls are drawn at random (without replacement) from the urn. Find the probability distribution of the number of white balls.

A box B_(1) contains 1 white ball, 3 red balls, and 2 black balls. An- other box B_(2) contains 2 white balls, 3 red balls and 4 black balls. A third box B_(3) contains 3 white balls, 4 red balls, and 5 black balls. If 2 balls are drawn (without replecement) from a randomly selected box and one of the balls is white and the other ball is red the probability that these 2 balls are drawn from box B_(2) is
