TopNewestI AM HERE GIVING THE SOLUTION......TODAY I WOULD POST A NEW QUESTION....:).... If the integer is 1 its probability is log(1),if the integer is 2 its probability is log(2),if the integer is 3 its probability is log(3)……likewise if the integer is n then its probability is log(n)……..let A denote the statement that the chosen number is even…..and B denote the statement that the chosen number is 2…. So (A intersection B)=2……hence the required probability is P(B/A)=[P(A intersection B)]/P(A)=P(B)/P(A)=log(2)/[log(2)+log(4)+log(6)+log(8)+…….log(2n)] =log(2)/log[(2^n)

n!]=log(2)/[nlog(2)+log(n!)]………….thanx for joining....:).....try my new problem..... – Raja Metronetizen · 3 years, 8 months agoLog in to reply

I am getting the answer as \(\frac{log(2)}{n*log(2) + log(n!)}\) – Saurabh Dubey · 3 years, 8 months ago

mine is the same.....then, you are right absolutely........could you prove your result.......??......:)Log in to reply

Should not the answer be \( \frac {log(2)}{n} \)? – Aditya Parson · 3 years, 8 months ago

Since number of positive even integers for first \(2n\) numbers is simply \(\frac{2n}{2}=n\). And, probability of getting 2 from all even integers can be expressed as \(\frac{log 2}{n}\), according to the questionLog in to reply

sorry,your understanding about the question is wrong....please go through the question minutely.....you have not understood it......try it...best of luck....:)Log in to reply

Can you point out my mistake, given that you have already solved it.Log in to reply

– Raja Metronetizen · 3 years, 8 months ago

i have already solved it.....:)...here you must think of conditional probability......that's my last hint.....try to think of this statement.......when we pick a number it is 2 given that the number is even........now i have almost said you what to do.......best of luck.....:)Log in to reply
