Aditi Saxena answered |
Class Mark = (Upper Limit + Lower Limit)/2
So, for the given problem;
Class mark = [(95+100)/2] = 97.5
Thus, class mark is 97.5.

Number of Possible Outcomes when Throwing a Die
The correct answer is option 'A' - 6.
Explanation:
A die is a cube-shaped object with six faces, each containing a different number ranging from 1 to 6. When a die is thrown, there are several possible outcomes or results.
Here's a detailed explanation:
1. Understanding the Die:
- A die is a solid object with six faces.
- Each face of the die has a different number from 1 to 6.
- The numbers on opposite faces of the die always add up to 7.
2. Possible Outcomes:
- When throwing a die, the possible outcomes are determined by the number of faces on the die.
- Since a die has six faces, there are six possible outcomes when it is thrown.
- These outcomes are the numbers displayed on the top face after the die comes to rest.
3. Identifying the Total Number of Possible Outcomes:
- To find the total number of possible outcomes, we count all the different numbers that can appear on the top face of the die after it is thrown.
- Since the die has six faces with different numbers (1, 2, 3, 4, 5, and 6), the total number of possible outcomes is 6.
4. Other Options:
- Option 'B' (36) is incorrect because it represents the total number of possible outcomes when two dice are thrown simultaneously. In this case, each die has six possible outcomes, resulting in a total of 6 x 6 = 36 outcomes.
- Option 'C' (2) is incorrect because it does not accurately represent the number of possible outcomes when throwing a single die.
- Option 'D' (None of these) is incorrect as it does not reflect the correct answer.
In conclusion, when a die is thrown, the total number of possible outcomes is 6, as each face of the die represents a different number.
The correct answer is option 'A' - 6.

Shubham Sharma answered |
The frequency of a particular data value is the number of times the data value occurs. For example, if four students have a score of 80 in mathematics, and then the score of 80 is said to have a frequency of 4. The frequency of a data value is often represented by ' f '.

Amit Kumar answered |
Non - red ball = 8
Probability = No of non red balls/Total no. of outcomes
= 8/10 = 4/5
Probability = No of non red balls/Total no. of outcomes
= 8/10 = 4/5

Class interval refers to the numerical width of any class in a particular distribution. It is defined as the difference between the upper-class limit and the lower class limit. Class Interval = Upper-Class limit – Lower class limit.

Kavya Saxena answered |
We know that in a single thrown of two die, the total number of possible outcomes is (6 × 6) = 36. Let S be the sample space. Then, n(S) = 36
When two dice are thrown, each die has 6 faces, numbered from 1 to 6. To find the total number of outcomes when both dice are thrown, you can use the multiplication principle.
- Outcomes for the first die: There are 6 possible outcomes (1, 2, 3, 4, 5, 6).
- Outcomes for the second die: Similarly, there are also 6 possible outcomes.
To find the total number of outcomes when both dice are thrown, multiply the number of outcomes for the first die by the number of outcomes for the second die:
Total Outcomes=Outcomes for the first die×Outcomes for the second die=6×6=36\text{Total Outcomes} = \text{Outcomes for the first die} \times \text{Outcomes for the second die} = 6 \times 6 = 36Total Outcomes=Outcomes for the first die×Outcomes for the second die=6×6=36
Conclusion
So, when two dice are thrown, there are a total of 36 possible outcomes. Each outcome can be represented as an ordered pair (x, y), where x is the result from the first die and y is the result from the second die. For example, (1, 1), (1, 2), ..., (6, 6).

A pie chart (or a circle chart) is a circular statistical graphic which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.
