Find the probability that both the balls are of blue color. Statement I: In a bag containing 4 red balls, 6 blue balls and 8 yellow balls, two balls are drawn at random one by one without replacement. Statement II: First ball is blue and if this happens then 5 more blue balls are added in the bag Statement III: Total blue balls are twice more than the other balls at the end of the drawing of balls
A box contains balls of two colours, black and white. A total of 28 balls were taken out from the box constituting of 1/5 of the black balls and 1/10 of the white balls. When 3/4 of the remaining black balls and 2/3 of the remaining white balls were also taken out, only 50 balls were left in the box. How many total balls were initially there in the box?
A box contains 50 balls, in which 5 are red balls, 6 are green balls, 9 are blue balls, and the remaining are yellow balls. Quantity I: Probability of picking 2 balls such that one is green and the other one is blue Quantity II: Probability of picking 3 balls such that at least one of them is red Quantity III: Probability of picking 3 balls such that at least one of them is blue
In the following question, 3 statements are given. You have to find which is/are necessary and sufficient to answer the following question. Two containers each contain some balls of Red and Blue color. Now all the balls of these two containers are mixed into a single third container which also contained some Red and Blue color balls initially as well. If 5 balls are taken out, then find the probability that all the balls taken out are Red in color. Statement 1∶ Total number of balls finally in 3rd container is 135. Statement 2∶ Ratio of balls in 1st container and 2nd container is 2 ∶ 7 Statement 3∶ Ratio of Red and Blue balls in 3rd container before mixing is 2 ∶ 3
Given below are two quantities named A and B. Based on the given information, you have to determine relation between the two quantities. You should use the given data and knowledge of Mathematics to choose between the possible answers. Quantity A: Number of hemispheres that can be formed by melting a sphere having volume equal to the volume of right circular cylinder whose diameteris 6 cm and height is 4 cm. Also, radius of hemisphere formed is half the radius of sphere from which the hemisphere is formed. Quantity B: Number of ice cream cones that can be made from a right circular cylinder shape ice cream container having radius 6 cm and height 5 cm. Ice cream cone to be made should have height 4 cm and slant height 5 cm and there should be a hemisphere made on top of the cone having radius equal to the radius of cone.
Ashutosh has a box containing 8 identical red balls, 9 identical blue balls and 10 identical green balls. He is required to distribute all these balls into three bags A, B and C such that the total number of balls in bag A is more than that in bag B, which, in turn, is more than that in bag C. Moreover, he needs to ensure that the number or red balls in bag A is more than that in bag B which in turn is more than that in bag C, and similarly for the blue and green balls. In how many ways can he do this? Each bag must contain at least one ball of each type.
