We call a prime $p$ "good" if there is $0<k<\log p$ with $2kp+1$ prime. What is the asymptotic density of good primes?

$\begingroup$ What is being chosen randomly here - I guess $p$? How is $p$ chosen randomly? $\endgroup$– Will SawinCommented Sep 4, 2021 at 17:16

$\begingroup$ Call a prime $p$ "good" if there is $k < \log p$ with $2kp+1$ prime. You're asking for the relative asymptotic density of good primes. $\endgroup$– mathworker21Commented Sep 4, 2021 at 17:51

$\begingroup$ It's a better way to ask my question ...Thanks $\endgroup$– Emmanuel GuilleminCommented Sep 4, 2021 at 18:51

3$\begingroup$ The density of all primes is zero, so as asked, the question is trivial. I think you are more interested in how many good primes there are up to $x$, asymptotically as $x\to\infty$. $\endgroup$– GH from MOCommented Sep 4, 2021 at 20:41
