Question # 1

Define the binomial probability distribution.

Ans 1: If P is the prbabilyt of success in a single trial and q is teh probability of failure, then the probability of exactly x successes in a n trials of a binomial expriment.

Question # 2

Write down two properties of binomial experiment.

Ans 1:
1. The outcomes of each trail may be classified into two categories i.e success and failure.
2. The replaced trails are independent.

Question # 3

Define hypergeometric random variable.

Ans 1: The random variable X which represents the number of successes in a hypergeometric experiment is called a hypergeometric ranodm variable, it is a dscrete variable which can assume any of the values x = 0,1,2,....... n,

Question # 4

What is Bernoulli trail?

Ans 1: A trail having two possible outcomes is called Bernoulli trail.

Question # 5

State the properties of the hyperogemoetric experiment.

Ans 1: 1- Each trial of the hypergeometric experiment results in an outcome that can be classified into one of the two categories, success or failure.
Ans 2: 2- The successive trials are dependent.
Ans 3: 3- The probability of success changes from trial to trial.
Ans 4: 4- The experiment is repeated a fixed number of times.

Question # 6

What are Bernoulli trials.

Ans 1: Repeated independent trials in which there are only two possible outcomes and probabilites of the outcomes remain the same for all trials are called Bernoulli trials.

Question # 7

Defile Binomial Experiment.

Ans 1: An experiment in which the outcomes can be classified as success or failure and probability of success remain constant from trail to trail is called a binomial experiment.

Question # 8

Identify the parameters of the binomial distributiion b( x; n,p) and the hypergeometric distribution h( x;N,n,h)

Ans 1: The binomial distribution b (x; n,p) has two parameters n and p, whereas the hypergeometric distribution h ( x; N; n,k) has three parameters N, n and h

Question # 9

What is a hypergeometric experiment.

Ans 1: An experiment in which a random sample is selected without replacement from a finite population is called a hypergeometric experiment. Here the successive trials are not independent and the probability of success does not remain the same from one trial to the other.

Question # 10

Describe the application of the binomial distribution.

Ans 1: The binomial distribution is applicatble to a wide variety of practical problems as well as to problems of an artificial sort, such as those dealing with cards, dice, coins and coloured balls in boxes.
Ans 2: It can be applied to any industrial situation where an outcome of a process is dischotomous and the results of the process are independent with a probability of success beng the same from trial to trial.
Ans 3: It is also used in medical and military situations. A drug eigher curse or does not cure the disease. A missible either hits or does not bit the target.
