information theory "clever student notices that"

とかでぐぐってばっちし見つけました．．

Problem 1.4:
The weatherman’s record in a given city is given in the table below, the numbers indicating the relative frequency of the indicated event.

　　　　　　　　　　　　Actual
　　　Prediction　　 Rain　　 No rain
　　　　Rain 　　　　1/8 　　　3/16
　　　　No rain　　 1/16 　　10/16

A clever student notices that the weatherman is right only 12/16 of the time, but could be right 13/16 of the time by always predicting no rain. The student explains the situation and applies for the weatherman’s job, but the weatherman’s boss (who has studied information theory) turns him down. Why?
