The number of eggs laid by some aquarium fish has a Poisson distribution with parameter λ. Each egg survives independently of anything else with probability p. Given that the number of survived eggs is S find the expected number of eggs produced by the fish. Can you give an intuitive explanation of your result? 這是我們老師出的題目 實在沒什麼 idea 有人可以解出來嗎 謝謝...... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 64.131.239.102 ※ 編輯: dounts 來自: 64.131.239.102 (08/06 00:05)
