a radio transmission tower is designed for a ''50-year wind'',that is,a wind
velocity having a return period of 50 years .find the probability that a
second 50-year wind will occur exactly on the fifth year after the
completion of the structure
中文大略翻:一无线电塔设计承受50年的风，此风再生期50年.找出此风在第5年发生第2次
的机率是多少
请问一下要怎麽解
谢谢
