Take a stick of unit length and break it into two pieces, choosing the break point at random. Now break the longer of the two pieces at a random point. What is the probability that the three pieces can be used to form a triangle? 想請問大家覺得該怎麼解? 我令一推隨機變數越來越複雜... 謝謝.. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 122.126.21.13
