Abstract
The copula function is considered on of nonparametric function which is easily implement able and opening wide door to find a lot of bivariate distribution in this paper clayton's copula has been used to find the bivariate exponational distribution then to find survival rate through the use of real data for two applications the pediatric control hospital and sample from Ghazi Al Hariri hospital by using bivariate distribution between two variable with a known depending value and calculate the probabilities of survival time results by the research it was proved that whenever to be yellow disease ratio is high to blood ratio in human with age is high whenever to be survival time is low. Second application is show to ill age to pass 60 years, whenever to be medicine active in treatment is low.
