推 TOOYA:T_i~exp(1/50) P(4<T_1+T_2<5)?? 03/02 01:55
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:一無線電塔設計承受50年的風，此風再生期50年.找出此風在第5年發生第2次
的機率是多少
請問一下要怎麼解
謝謝
