- A. Probability
- B. Statistics
- C. Both the options
- D. None of the options
Remarks:
Explanation:
Statistics holds the responsibility of describing the data collected.
Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It provides a set of methods and tools that can be used to describe, analyze, and make inferences about data.
Probability, on the other hand, is a branch of mathematics that deals with the study of random events and the likelihood of their occurrence. It is often used in conjunction with statistics to make predictions and draw conclusions about data.
Therefore, statistics holds the responsibility of describing the data collected, while probability is used to study the likelihood of events and outcomes.

- A. Exhaustive Event
- B. Simple Event
- C. Non-mutually Exclusive Event
- D. Mutually Exclusive Event
Remarks:
Explanation:
Non-mutually Exclusive Event
A non-mutually exclusive event is an event that can occur simultaneously with another event. In this case, drawing either a King or a Queen card from a deck of cards are not mutually exclusive events, since a card can be both a King and a Queen (the Queen of Hearts, for example). The probability of drawing either a King or a Queen card is calculated by adding the probability of drawing a King card to the probability of drawing a Queen card, minus the probability of drawing a card that is both a King and a Queen (which is zero in this case).
In contrast, mutually exclusive events are events that cannot occur at the same time, such as drawing a King card and a Queen card from the same deck of cards. Simple events are the most basic outcomes of an experiment, while exhaustive events cover all possible outcomes of an experiment.

- A. Uniform Distribution
- B. Normal Distribution
- C. Binomial Distribution
- D. Poisson Distribution
Remarks:
Explanation:
The correct answer is "Poisson Distribution". The Poisson distribution is a discrete probability distribution that is often used to model the number of events occurring in a fixed interval of time or space, given the average number of events that occur during that interval. It is commonly used in fields such as insurance, finance, and telecommunications to model rare events such as accidents, equipment failures, or phone calls received per unit of time. The Poisson distribution is characterized by a single parameter λ (lambda), which represents the average rate of occurrence of the event.
- A. Hypothesis Testing
- B. Statistical Hypothesis
- C. None of the options
Remarks:
Explanation: The correct answer is "Hypothesis Testing". Hypothesis testing is a formal statistical procedure used to make decisions about whether to accept or reject a hypothesis. It involves formulating a null hypothesis and an alternative hypothesis, collecting data, and using statistical methods to determine the likelihood that the data is consistent with the null hypothesis. If the data is unlikely to have occurred by chance alone, the null hypothesis is rejected in favor of the alternative hypothesis. Hypothesis testing is widely used in fields such as science, engineering, and business to make informed decisions based on empirical evidence.
- A. Median
- B. Mean
- C. Mode
- D. All the options
Remarks:
Explanation:
The correct answer is "All the options". The measures of central tendency are a set of descriptive statistics that provide information about the center of a distribution or a dataset. The three most commonly used measures of central tendency are the mean, median, and mode.
The mean is the arithmetic average of a dataset, and it is calculated by adding up all the values and dividing by the number of values.
The median is the middle value of a dataset, and it is the point that divides the data into two equal halves.
The mode is the value that appears most frequently in a dataset.
All three measures of central tendency are important in different contexts, and they can provide different insights into the characteristics of a dataset.
