<p>I did not originally ask the question below that was closed, but would appreciate some clarity so I can better understand SE Q&amp;A policies. The generic reason given for closure was that it was off-topic. More specifically, it was stated in comments by <a href="https://stats.stackexchange.com/users/919/whuber">whuber</a> that it was a self-study question and was in violation of self-study policies.</p>
<p><a href="https://stats.stackexchange.com/questions/522562/memoryless-property-how-does-px-s-t-mid-x-s-px-t-s-t-ge-0-i">Memoryless property: how does $P(X &gt; s + t \mid X &gt; s) = P(X &gt; t), s, t \ge 0$ imply that $F^c(s + t) = F^c(s) F^c(t), s, t \ge 0$?</a></p>
<p>I am unable to understand why this question was determined to be a self-study question. Please may someone assist me in understanding what features of this question rendered it so, resulting in its closure?</p>
