a NATO aircraft files directly over a building in Kpsovo and fires a single air-to-surface missile. if the missile hits anywhere within 30 feet of the building, major structural damage will be incurred. suppose that with a certain sighting device, the probability function describing the missile's point of impact is given by f(x)= 60+x/3600 for -60<x<0 60-x/3600 for 0<=x<60 where x is the perpendicular distance from the building to the point of impact. find the probability of the event marjor structural damage is incurred. 請問大家這題怎麼算??? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.133.92.110

P(-30 < X < 30) = P(-30 < X < 0) + P(0 < X < 30)
