Binomial Distribution with non integer succes

In summary, when determining the probability that the number of students wanting a new book is within two standard deviations of the mean, you may encounter a non-integer number when using the equation μ +- 2δ. In order to find the probability, this number should be rounded and used in the factorial calculation. For example, if μ - 2δ is 12.3 and μ + 2δ is 17.8, then the number of students wanting the book is within two standard deviations of the mean when the number of students is 13, 14, 15, 16, or 17. This can be extrapolated to other similar scenarios.

I am doing a problem where I am to determine the probability that the number of students wanting a new book is within two standard deviations of the mean. μ +- 2δ comes out with a non integer number, in which I have to use to find probability. The equation to find probability uses the factorial of this number. Do I round this number to determine the factorial?

well if [itex]\mu - 2 \delta[/itex] is 12.3 and [itex]\mu + 2 \delta[/itex] is 17.8 then the number of students wanting the book is within two standard deviations of the mean when the number of students wanting the book is 13, 14, 15, 16, or 17. You can extrapolate.
 

What is the Binomial Distribution with non-integer success?

The Binomial Distribution with non-integer success is a probability distribution that describes the likelihood of a certain number of successes in a fixed number of trials, when each trial has a probability of success that is not a whole number. It is used to model situations where the probability of success is continuous, such as in genetics or finance.

How is the Binomial Distribution with non-integer success different from the regular Binomial Distribution?

The regular Binomial Distribution assumes that the probability of success for each trial is a whole number, while the Binomial Distribution with non-integer success allows for continuous probabilities of success. This makes it more flexible and applicable to a wider range of situations.

What is the formula for calculating the Binomial Distribution with non-integer success?

The formula for calculating the Binomial Distribution with non-integer success is: P(x) = (nCx) * p^x * (1-p)^(n-x), where n is the number of trials, x is the number of successes, and p is the probability of success for each trial.

How can the Binomial Distribution with non-integer success be used in real-life situations?

The Binomial Distribution with non-integer success can be used to model a variety of real-life situations, such as predicting stock prices, analyzing the success rate of medical treatments, or predicting the likelihood of genetic traits being passed down in a family.

What are the limitations of the Binomial Distribution with non-integer success?

The main limitation of the Binomial Distribution with non-integer success is that it assumes that each trial is independent and has the same probability of success. It also assumes that the trials are conducted under identical conditions, which may not always be the case in real-life situations.
