What is wrong in his method althrough i checked correctly PS: we can use Generating Functions also to solve this question!

http://math.stackexchange.com/questions/540215/probability-of-getting-a-sum-of-13 This Link Clearly Shows you all work, I'm very happy that i Proved That Your Physics Forum Mentor is wrong! @D H Mentor:First You work out the question then post appropriate Comment,PLEASE DON'T MISGUIDE a...

Your Approach is wrong,and This eventually leads to Obvious Wrong Answer! The Answer is:25/162.

may be u r saying Lie,probaility(saying a Lie)= 0.5.. ok,what is the answer that you got?

it will take more than half-an hour,but in Exam it won't entertain such silly tasks!

your approach is correct upto 3 dice,but u cannot do for 4 dice

yes,it's easy,but here we have to find when four dices rolled together..

Obtain the probability of getting a sum of 13, when four fair dice are rolled together once. if we do by just calculating all possible values of sum,then it will take more time. so,we can do above problem as Multinomial Coefficents of sum i.e.,x1+x2+x3+x4 = 13 where,1<= xi <= 6,for all 1<= i <=...

what is the approach for this problem?

Hi everyone, So I am taking a statistics course and finding this concept kinda challenging. wondering if someone can help me with the following problem! Let X be a random variable with probability density function $$f(x)=\begin{cases}xe^{-x} \quad \text{if } x>0\\0 \quad \text{ }...
