We wish to select 2 black and 3 red balls from a bag containing 5 black and 6 red balls. Find the number of ways in which this can be done.

A bag contains 5 black and 6 red balls. Determine the number of ways in which 2 black and 3 red balls can be selected.

Bag I contains 4 black and 6 red balls, bag II contains 7 black and 3 red balls and bag III contains 5 black and 5 red balls.One of the bag is selected at random and a ball is drawn from it. The ball is found to be red. Find the probability that ball is drawn from Bag I.

Bag I contains 4 black and 6 red balls, bag II contains 7 black and 3 red balls and bag III contains 5 black and 5 red balls. One bag is chosen at random and a ball is drawn from it which is found to, be red. Find the probability that the ball is drawn from bag II.

Bag I contains 2 black and 8 red balls, bag II contains 7 black and 3 red balls and bag III contains 5 black and 5 red balls. One bag is chosen at random and a ball is drawn from it which is found to be red. Find the probability that the ball is drawn from bag II.

A bag contains 10 white, 6 black and 4 red balls. Find the probability of getting : a black ball

A bag contains 10 white, 6 black and 4 red balls. Find the probability of getting : not a red ball

A bag contains 10 white, 6 black and 4 red balls. Find the probability of getting : a white ball

A bag A contains 4 black and 6 red balls and bag B contains 7 black and 3 red balls. A die is thrown. If 1 or 2 appears on it, then bag A is chosen, otherwise bag B is chosen. If two balls are drawn at random from the selected bag, find the probability of one of them being red and the other black.
