Direction: There are three boxes P, Q and R which consists of Red, Blue and Green colour balls. Total number of blue balls in all three boxes together is 9 and total number of balls in all the boxes together is 32.
In Box P: The probability of choosing a Blue ball is 1/4 and the number of red balls is 2 more than the number of blue balls.
In Box Q: Total number of balls is 10 and the ratio of probability of getting a Blue and a Red ball is 2 : 3. Also the sum of Blue and Green balls is 4 more than the number of red balls.
In Box R: Total number of balls is 10 and the probability of getting a red is 1/5 less than the probability of getting a blue.
What is the probability of getting either a blue or a green ball from box R.
3/5
2/5
4/5
7/10
1/2
Certainly! Let's break down each statement and option:
- Box P:
- Probability of blue ball = 1/4. Hence, number of blue balls = 1/4 * total balls in Box P.
- Let blue balls = x. Then total balls = 4x.
- Red balls = x + 2.
- Box Q:
- Total balls = 10.
- Ratio of probability (Blue:Red) = 2:3.
- Let the number of blue balls = 2a and red balls = 3a.
- Blue + Green balls = Red balls + 4. Hence, 2a + Green balls = 3a + 4. Green balls = a + 4.
- Box R:
- Probability of red = 1/5 less than blue. Hence, if blue = b/10, then red = (b/10) - 1/5.
- Total Red and Blue = probability b + (b/10 - 1/5).
- Let’s solve for options:
- Option 1: 3/5
- Option 2: 2/5
- Option 3: 4/5
- Option 4: 7/10
- Option 5: 1/2
- Correct Answer: The probability of getting either a blue or a green ball from Box R is 4/5.
