**Q.4. Define mutually exclusive events and exhaustive events. **

**Ans. Mutually Exclusive Events:** A set of events is said to be mutual if the occurrence of any other that is at most one of the events can occur. **Exhaustive Events:** A set of events is said to be mutually exclusive if the occurrence of events can occur.

**Q.5. What is meant by actual frequency distribution?**

**Ans.** Actual frequency distribution is also known as ‘observed frequency distribution’. It is constructed on the basis of data available or observed in statistical experiments.

**Q.6. Define the term theoretical frequency distribution.**

**Ans.** Theoretical frequency distribution is also called ‘expected or probability of model frequencies distribution as a distribution of frequencies which is not based on actual experiments or observations but is constructed through expected frequencies obtained by mathematical computation based on certain hypotheses.

**Q.7. Write the four types of discrete theoretical distribution. **

**Ans.** The four types of discrete theoretical distribution are as follows:

- Binomial distribution,
- Poisson distribution,
- Negative binomial distribution,
- Geometric distribution.

**Q.8. Write the four types of a continuous probability distribution. **

**Ans.** The four types of the continuous probability distribution are:

- Normal distribution,
- Student’s t-distribution,
- Chi-square distribution,
- F-distribution.

**Q.9. Write the definition of the binomial distribution.**

**Ans.** The binomial distribution is a discrete frequency distribution, which is based on dichotomous alternatives, le. on the basis of the probability of data of success (desired event) and failure. This distribution, in the form of a probability density function, can be expressed as follows:

- P(x) = “Cxqn-* pt
- P(r) =”Crqn-‘p

**Q.10. Discuss the four assumptions of the binomial distribution. **

**Ans.** The four assumptions of the binomial distribution are:

- A finite number of trials,
- Mutually exclusive outcomes,
- Same probability in each trial,
- All trials independent.

**Q.11. Write the three general rules of binomial expansion methods. **

**Ans.** The three general rules of binomial expansion methods are:

- Number of terms,
- The sequence of exponents,
- Sum of exponents.
