There are 6 red and 8 green balls in a bag. 5 balls are drawn at random and placed in a red box. The remaining balls are placed in a green box. What is the probability that the number of red balls in the green box plus the number of green balls in the red box is not a prime number?

There are 6 red balls and 6 green balls in a bag. Five balls are drawn out at random and placed in a red dox. The remaining seven balls are put in a green box. If the probability that the number of red balls in a green box plus the number of green ball in the red box is not a prime number, is p/q where p and q are relativey prime, then find the value of (p+q).

There are 5 red and 7 green balls in a bag. Three balls are drawn from it. Find the probability that 1 ball is red & 2 balls are green .

In a box there are 6 blue ball, X red balls & 10 green balls. Probability of choosing one red ball from the given box is 1/3, then find the sum of red and blue balls in the box?

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.

There are 5 blue , 6 red and 7 green balls in a bag . If a ball is picked up at random ,what is the probability of getting a non blue ball ?

In a box there are12 blue ,X red balls & green balls , probability of choosing one red ball from the given box is (1)/(3) .Then find the sum of red and blue balls in the box?

A bag contains 2 red,3 green & 2blue balls. Two balls are drawn at random.What is the probablity that none of the balls drawn is blue?
