Thread: binomial distribution

i could really do with some help with this for my coursework.

basically i rolled five dice 200 times and had to write down how many times i got a 6 in each throw.
now i have to do the binomial distribution with the results and then the chai square

does anyone know what to do. i dont really understand all of the text available on the internet

Please do not post the same question twice as you have posted here as well: http://www.mathhelpforum.com/math-he...tribution.html

You want to know the expected number of 6's thrown in total or each time? Each time, the expected amount is simply . Likewise, multiply that by 200 for the total expected amount of 6's. There is no use for Binomial or Chi-Square unless you have a specific question such as the expected amount of throws with 2 or more 6's. That question used Binomial properties of probability.

id posted it in urgent homework help and then saw this section and thought it would be more relevent to the question.

the question states firstly to "use binomial distribution to model the data and calculate the expected frequencies using you model"
and then the next question says "use a chai squared test to decide whether the dice may be considered fair"
