A bag contains 12 red balls 6 white balls. Six balls are drawn one by one without replacement of which at least 4 balls are white. Find the probability that in the next two drawn exactly one white ball is drawn. (Leave the answer in `""^(n)C_(r )`).

A bag contains 4 green and 6 white balls. Two balls are drawn one by one without replacement. If the second ball drawn is white, what is the probability that the first ball drawn is also white ?

A box contains 4 red and 8 white balls. If 4 balls are drawn one by one with replacement then the probability of getting 3 white balls 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 box contains 4 red and 8 white balls . If 4 balls are drawn one by one with replacement then the probability of getting 3 white balls is

A box contains 4 red and 8 white balls . If 4 balls are drawn one by one with replacement then the probability of getting 3 white balls is

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 all are white?

A box contains 12 red and 6 white balls. Balls are drawn from the bag one at a time without replacement. If in 6 draws, there are at least 4 white balls, find the probability the exactly one white ball is drawn in the next two draws. (Binomial coefficients can be left as such.)
