Manish Singh answered
The total no .of possible outcomes = 6 
                  No .of favourable outcomes = 3 (2,3,5)
Let this event be E . p(E) = No . of favourable outcomes / total no .of outcomes 
                                      = 3/6 .
                                      = 1/2
So , probability of getting a prime number is 1/2

The probability that a non leap year selected at random will contain 53 Sunday's is
  • a)
    1/7
  • b)
    2/7
  • c)
    3/7
  • d)
    5/7
Correct answer is option 'A'. Can you explain this answer?

Amit Kumar answered
A non-leap year has 365 days
A year has 52 weeks. Hence there will be 52 Sundays for sure.
52 weeks = 52 x 7 = 364 days .
365– 364 = 1 day extra.
In a non-leap year there will be 52 Sundays and 1day will be left.
This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday, friday, Saturday, Sunday.
Of these total 7 outcomes, the favourable outcomes are 1.
Hence the probability of getting 53 sundays = 1/7.

Arpita Nambiar answered
The correct court to which a consumer can approach with a claim of Rs. 40 lakhs is the State Consumer Court.

Explanation:

The Consumer Protection Act, 2019 provides for the establishment of three-tier consumer dispute redressal mechanism:

1. District Consumer Disputes Redressal Commission at the district level
2. State Consumer Disputes Redressal Commission at the state level
3. National Consumer Disputes Redressal Commission at the national level

The jurisdiction of these courts is determined by the value of the claim:

1. District Consumer Disputes Redressal Commission: Up to Rs. 20 lakhs
2. State Consumer Disputes Redressal Commission: Between Rs. 20 lakhs and Rs. 1 crore
3. National Consumer Disputes Redressal Commission: Above Rs. 1 crore

Therefore, in the given scenario, since the claim amount is Rs. 40 lakhs, the appropriate court for the consumer to approach would be the State Consumer Disputes Redressal Commission.

Anjali nair answered
Understanding the Problem
When a fair die is rolled, it can land on any of the six faces, which are numbered from 1 to 6. The question asks for the probability of rolling a number x such that 1 < x="" />< 6.="" />Identifying the Valid Outcomes
- The numbers that satisfy the condition 1 < x="" />< 6="" are:="" -="" 2="" -="" 3="" -="" 4="" -="" 5="" />Counting the Successful Outcomes
- There are four successful outcomes (2, 3, 4, 5) that meet the criteria.
Total Possible Outcomes
- A die has a total of six outcomes (1, 2, 3, 4, 5, 6).
Calculating the Probability
- The probability of an event is calculated as:
- Probability = (Number of Successful Outcomes) / (Total Possible Outcomes)
- In this case:
- Successful Outcomes = 4 (which are 2, 3, 4, 5)
- Total Outcomes = 6
- Therefore, Probability = 4/6 = 2/3
Conclusion
- The probability of rolling a number x such that 1 < x="" />< 6="" is="" not="" 1,="" but="" rather="" 2/3,="" which="" falls="" between="" 0="" and="" />
thus, the correct answer is option c) between 0 and 1.

The following are the reasons for consumer exploitation:

1. Illiteracy and Ignorance of the Consumer:
The majority of the population have less knowledge about the quality of a good and they are ignorant about it. Due to these weaknesses they are be-fooled.

2. Fatalism of Consumer:
Many consumers never analyze the quality of the good and the price. They feel whatever they get is a gift of god and at the best price.  

3. Compromising Attitude:
Many consumers easily let go complaints and issues. They don’t complain about it rather compromise with what they have.

4. Unrecorded Sales:
Many producers don’t give receipt or cash memo of what a consumer buys. Hence no case can be lodged against them. Consequently we are cheated and no one can save us.

The consumer must provide evidence of the damage caused by the product, such as photographs, receipts, or medical reports, to support their claim. The consumer forum or commission will then investigate the complaint and determine the appropriate compensation to be awarded.

The compensation awarded may include the cost of the product, any medical expenses incurred due to the product, and compensation for mental agony and harassment caused by the product.

In conclusion, the Right to Seek Redressal is an important right granted to consumers that allows them to claim compensation for any damage caused by a product.

The sum of the probabilities of all elementary events of an experiment is p, then
  • a)
    0 < p < 1
  • b)
    0 > p > 1
  • c)
    p = 1
  • d)
    p = 0
Correct answer is option 'C'. Can you explain this answer?

Kds Coaching answered
 According to the basic axiom of probability, the sum of the probabilities of all individual outcomes in any experiment is always 1 because the sample space includes every possible outcome. Option A suggests a range that does not include 1, option B presents an invalid inequality, and option D indicates a probability of 0, which contradicts the fundamental principle that probabilities in a complete sample space must total 1.
So option C is correct
