General + Binomial Distribution

Question 1

Answer 1

Distinct Definite Values.

Question 2

Answer 2

Values over an interval.

Question 3

What is Random Variables?.

Answer 3

Takes several values with different/same probabilities.

Question 4

What is Discrete Random Variable?

Answer 4

An exact distinct definite value that varies based on its probabilities.

Question 5

Head & Tail (Coin Tosses)

Answer 5

Probability;

AND - XA discrete random

OR - +

Question 6

What are the 2 types of data?

Answer 6

I. Discrete
II. Continuous

Question 7

What is Binomial Distribution, formula, and notation?

Answer 7

A discrete random variable of X is said to follow the B.D with parameters ‘n’ & ‘p’ if it p.d.f is given as follows…. (Formula)

- N - Number of repetitions/trials
- P - Probability of success
- Q - Probability of failure ~

E(X) - np
Var(X) - npq

Question 8

What are the conditions for Binomial Distribution?

Answer 8

1. The random variable under study should be discrete.
2. The number of trials/repetitions should be small. (n<20/n<30)
   3. The probability of success remains constant from trial to trial. Vis-versa
   4. The trials are independent of each other.
   5. Each trial results in one of 2 outcomes, that is either a success or a failure. (B.T)

Question 9

How many trials does B.D has?

Answer 9

Finite trials (Know where it stops.)
