If a sentence has ten characters, the chance of getting the whole sentence correct even just for pronunciation is only 90 raised to a power of ten, which comes out to an accuracy rate of about 35 %. This is the reason why "Government Information Office" becomes "sex toys."
一個句子如果有十個字，那麼這個句子完全正確的機率就只有百分之九十的十次方，也就是只有三成五左右的正確率而已，這也就是「新聞局」會變成「性玩具」的原因。
