Typing errors in a text are either nonword errors, as when "the" is typed as "teh," or word errors that result in a real but incorrect word. spell‑checking software will catch non‑word errors but not word errors. human proofreaders catch 70% of word errors. you ask a fellow student to proofread an essay in which you have deliberately made 10 word errors. if the student matches the usual 70% rate, what is the distribution of the number of errors caught?
