hai, I want to perform a simulation like this£º Suppose that I have one population ,it's size is 500, is composed of x,y and z. The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries Resources, Ministry of Agriculture ,Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Qingdao 266071,China __________________________________________________ ÂÑÂÅ»¢ÂÃÂâ·ÂÑGÂÓÂÊÂÃÂä£ÂÂÂÖÂùÂúµÂÚÂÒ»¾ÂøÂÃŽÂÞÂÀ¬»ÂøÂÓÂʼÂþÂɧÂÈÂų¬´ÂóÂÓÂÊÂÃÂä
