Suppose four balls labelled `1, 2, 3, 4` are randomly placed in boxes `B_1, B_2,B_3,B_4.` The probability that exactly one box is empty is

Four balls numbered 1,2,3,4 are to be placed into five boxes numbered 1,2,3,4,5, such that exactly one box remains empty and no ball goes to its own numbered box.The no.of ways is

9 different balls are to be arranged in 4 different boxes number B_1,B_2,B_3 and B_4 . If the probability that B_3 has exactly three balls is k(3/4)^9 then find k

A box B_1 contains 1 white ball, 3 red balls and 2 black balls. Another 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 1 ball is drawn from each of the boxes B_1 , B_2 and B_3 , then the probability that all 3 drawn balls are of the same colour , is

If 12 indentical balls are to placed in 3 indntical boxes, then the probability that one of the boxes contains exactly 3 balls is

If 12 identical balls are to be placed in 3 identical boxes, then the probability that one of the boxes contains exactly 3 balls is
