The probability of drawing one white ball from a bag containing 6 red, 8 black , 10 yellow and 1 green ball is​

The probability of drawing a green coloured ball from a bag containing 6 red and 5 black balls is :

Find the probability of drawing a green coloured ball from a bag containing 6 red and 5 black balls.

The probability of drawing 2 red balls in succession from a bag containing 4 red balls and 5 black balls when the ball that is drawn first is not replaced is

In bag A there are 8 red balls ,X green balls and 6 yellow balls,probability of drawing one green ball from bag A is 3/5. bag B there are (X-3) red balls, (X-9) green balls and 6 yellow balls ,2 balls are drawn from bag B. Find the porbability that both the balls are red colour ?

A bag contains 4 white balls and some red balls.If the probability of drawing a white ball from the bag is (2)/(5), find the number of red balls in the bag.

The probability of drawing 4 white and 2 black balls in two drawings in succession from a bag containing 1 red,4 black and 6 white balls, if the drawing is without replacement

A bag constains white, black and red ball only. A ball is draw at random form the bage. If the probability of getting a white balls is (3)/(10) and that of a black ball is (2)/(5) then find the probability of getting a red ball. If the bag contains 20 black balls, find the total number of balls in the bag.

A bag contains 20 balls out of which x balls are white.If one ball is drawn at random,the probability drawing a white ball is y.Now place this ball and 10 more white balls in the bag.Now if a ball is drawn from the bag,the probability of drawing the white ball is 2y. Find x.

A bag contains 15 white and some black balls. If the probability of drawing a black ball from the bag is thrice that of drawing a white ball find the number of black balls in the bag.

A bag contains 15 white and some black balls. If the probability of drawing a black ball from the bag is thrice that of drawing a white ball, find the number of black balls in the bag.
