Homework: assume that of all mathematicians with an English-language social media account, 1 in 16 is working with expectations on any given day, of which 1 in 1024 comes up with the above joke, of which 1 in 8 decides to post it on their social media, of which 1 in 2 actually do so. Assume the decision whether to post is a Bernoulli trial.
Write down the expectation of the number of times the joke has been or will be made this calendar week (as of this post) given your current information.
E[ X | X ≥ 1 ], where X is a random variable of unknown distribution
