Raj picks two shoes from a bag containing 15 black shoes and 25 red shoes. What is the probability of Raj picking, at random, 2 shoes of different colours?

Raj picks two shoes from a bag containing 15 black shoes and 25 red shoes. What is the probability of Raj picking, at random, 2 shoes of different colours? Correct Answer 25/52

Given,

Number of black shoes = 15

Number of red shoes = 25

Required probability = (black and red) = 2 × (15/40) × (25/39) = 25/52

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. A bag contains some number of Diamond of 4 different colors (Red, Pink, blue and yellow). What is the total number of Diamond in the bag? I. If 5 Pink Diamond from the bag are replaced by Yellow Diamond, Then the ratio of probabilities of picking 2 yellow Diamond at a time to picking 3 Blue Diamond at a time becomes (1/116). II. The different between probabilities of picking 2 Red Diamonds at a time and probability of picking 2 Blue Diamonds at a time is (23/330). III. If a Diamond is picked from the bag, then there is 40% chance that it is a red Diamond. Probability of picking 2 Red Diamond from the bag is (26/165).
In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for the both quantities and choose the correct option. Quantity A: What is the probability of picking two balls, first red and second white without replacement, from a bag containing 10 red, 10 white and 5 black balls? Quantity B: What is the probability of picking first ball red, and after keeping it back, picking a second ball white, from a bag containing 10 red, 10 white and 5 black balls?
Compare the values of the two quantities in the question and answer. Quantity 1: A bag contains 20 balls which are red, green and blue. Find the number of red balls in the bag, if the probability of picking a blue ball is 2/5 and that of either a red or a blue ball is 3/4. Quantity 2: A bag contains 25 balls which are red, green and blue. The probability of picking a red ball first is 2/5. If the first ball was red and without keeping it back, probability of picking a blue ball is 1/3, find the number of green balls.
A box contains red, green, and blue colored balls, such that the probability of picking a blue ball is 37.5% of the probability of picking a red ball, and the probability of picking a red ball is 88.89% of the probability of picking a green ball. If the box contains 8 red balls, then how many total balls are there in the box?
A bag contains black and white balls, such that the probability of picking a black ball is 4/7. If the probability of picking two black balls without replacing the first is 4/13, how many black balls are there in the bag?
The following question has three statements. Study the question and the statements and decide which of the statement(s) is necessary to answer the question. In a box containing a total of 100 balls of colors, red, blue, green and yellow, find the number of blue balls. I) The probability of picking either a red or green ball is 13/20. II) The probability of picking either a blue or yellow ball is 7/20. III) The probability of picking a yellow ball is 3/20.
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.
A bag contains 4 red and 3 black balls. A second bag contains 2 red and 4 black balls. One bag is selected at random. From the selected bag, one ball is drawn. Find the probability that the ball drawn is red.
Bag A contains certain number of balls (red and green). Bag B has 60% more red balls than in bag A and 10% more green balls than in bag A. If the ratio of total balls in bag A to that in bag B is 10 : 13, then what is the ratio of red to the green balls in bag B?
