Take a look at the four requirements for binomial probability distributions:

1. Fixed number of single observations (trials)

2. Each trial is independent

3. Each trial must have outcomes that fall into one of two categories (success, failure)

4. The probability of success remains the same for every trial.

Come up with an example scenario in which you would have a binomial probability distribution to work with.

Expert Solution

Come up with an example scenario in which you would have a binomial probability distribution to work with.  

Let's say you have a MCQ test of 10 questions and you haven't studied for the same.

Each question has 4 options and you decided to answer the test by picking one card from the deck of 52 with replacement, if the card is spade you tick option A, if it is heart you tick B, if club then C and if diamond you tick D.

In each scenario the probability of ticking the correct answer is 1/4 for each question

1. Fixed number of single observations (trials)

10 questions

2. Each trial is independent

one question being correct or incorrect does not affect other

3. Each trial must have outcomes that fall into one of two categories (success, failure)

Either question is correct or incorrect

4. The probability of success remains the same for every trial.

For every question the probability of being correct is 1/4

Consider a binomial experiment with 20 trials and probability 0.35 of success on a single trial. (a) Use the binomial distribution to find the probability of exactly 10 successes. (Round your answer to three decimal places.) (b) Use the normal distribution to approximate the probability of exactly 10 successes. (Round your answer to three decimal places.) (c) Compare the results of parts (a) and (b). These results are fairly different. These results are almost exactly the same.
