A bag contas 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 oen white ball is 14400, then n is (A) 120 (B) 144 (C) 5 (D) 10

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 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 black balls. Pairs of balls are drawn without replacement untill the bat is empty. If the number of ways in which each pair consists of one black and one white balls is 576, the n is equal to (A) 5 (B) -4 (C) 24 (D) 12

A bag contains n white and n black balls . Pairs of balls are drawn at random without replacement successively , until the bag is empty . If the number of ways in which each pair consists of one white and one black ball is 14,400 then 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)/(^(2n)C_n)
