Overall, the majority of users failed this quiz. 29.7 percent of users got two right, while 25.8 percent got three right. Only 1.6 percent of users correctly identified all six WAV files, and only 4.5 percent got five correct.
比起二项分布B(6,1/3)有一点区别,然而“一耳朵”的差距是不太可能了————只有1.6%的人6首全对,当然,乱猜的话只有0.1%的概率全猜对……
