From a bag containing 6 red balls, 5 green balls and 3 blue balls, the probability of getting a green ball at random………

A bag contains some red and green balls If we take a ball from it, without looking the probability of getting a red ball is '1/4' a) What is the total number of balls, if there are 8 red balls? b) What is the probability that a ball taken is green? c) Find the sum of both the probabilities d) From a box containing some red balls and some blue balls the probability of getting a redball is ' a/ b' What is the probability of getting a blue ball?

From a bag containing 2 white and 6 green balls, a ball is drawn at random. The probability of not a green ball is :

In a bag, there are 2 rad balls, 3 green balls and 4 brown balls. Find the probability of drawing a ball at random being red or green.

IF a ball is drawn at random from a box containing 11 red balls,6 white balls and 9 green balls then, the probability that the ball is not green is

A bag contains 3 red, balls, 4 bule balls and 5 green balls .What is the probability that a ball picked up at random is not a blue ball ?

Two balls are drawn at random from a bag containing 6 red and 4 green balls, find the probability that both ball are of same colour.

A bag contains 4 red balls, 5 green balls, and 3 blue balls. If a ball is selected at random from the bag, what is the probability that the ball selected will be green ?

A bag contains 4 green balls,4 red balls and 2 blue balls.If a ball is drawn from the bag,the probability of getting neither green nor red ball is (2)/(5) (b) (1)/(2)(4)/(5) (d) (1)/(5)

A bag contains 4 green balls, 4 red balls and 2 blue balls. If a ball is drawn from the bag, the probability of getting neither green nor red ball is (a) 2/5 (b) 1/2 (c) 4/5 (d) 1/5

A box contains some green and blue balls. 7 red balls are put into it. Now the probability of getting a red ball from the box is 7/24 and that of a blue ball is 1/6 . How many balls are there in the box?
