A bag contains `n` white and `n` red balls. Pairs of balls are drawn without replacement until the bag is empty. Show that the probability that each pair consists of one white and one red ball is `(2^n)/(^(2n)C_n)`

A bag contains n white and n red balls.Pairs of balls are drawn without replacement until the bag is empty.Show that the probability that each pair consists of one white and one red ball is (2^(n))/(2nC_(n))

. A bag contains n white, n black balls. Pair of balls are drawn without replacement until the bag is empty. Then Find the probability that each pair consists of one white and one black ball is

A bag contains n white and n black balls. Pairs of balls are drawn without replacement until the bag is empty. If the number of ways in which each pair consists of one black and one white ball is 576, then n is

A bag contains n white and n red balls. Pairs of balls are drawn without replacement until the bag is empty. If the number of ways in which each pair consists of one red and one white ball is 14400, then n is: (A) 120 (B) 144 (C) 5 (D) 10

A bag contains 20 white balls and 20 red balls (Assume that balls of same colour are distinguishable). Pairs of Balls are drawn at random without replacement until the bag is empty. The probability that each pair consists of one white ball and one red ball is (a^(b)*(c!)^(d))/(e!) , then find the no of proper divisors of a+b+c+d+e

A bag contains 3 White,3 black and 2 red balls.One by one three balls are drawn without replacement.Find the probability that third ballis red

A bag contains 3 White, 3Black and 2 Red balls. 3 balls are successively drawn without replacement. Find the probability that third ball is red.

A bag contains 7 green,4 white and 5 red balls.If four balls are drawn one by one with replacement,what is the probability that one is red?

A bag contains 5 white, 4 black and 2 red balls. Balls are drawn one by one without replacement. The probability that the 5^("th") ball is a red ball, is
