Question

Which of the following probability situations most likely applies to a binomial distribution?

a. The probability that a friend of yours misses over half of the questions on her English exam.

b. The probability that your lab partner will obtain a score of atleast a 69 or higher on Computer Science exam.

c. The probability that your quiz will have difficult fill in the blank questions with 4 or fewer possible answers.

d. The probability that you will take not take the A&P final exam without studying for more than one hour at the local libarary.

Explanation / Answer

a is most appropriate situation.

Situations best apply to Binomial Distribution:

1)FIXED NUMBER OF TRIALS: The number of trials for conducting the random experiment must be fixed. Here, number of questions to be attempted or not is fixed.

2)Trials are independent: Here attempting or not attempting next question does not depend if your friend attempts the previous question or not.

3)Two Possible Outcomes of each trial:Success and Failure-

Here, attempting a question is Failure, missing a question is Success.

4)P(Success)=p or P(Failure)=1-p, is fixed in each trial:

P( Missing a question)=p

P(Attempting a question)=1-p

,in each trial.
