  In this paper, we introduce a new bivariate distribution we called it
bivariate expo- nentiated modified Weibull extension distribution (BEMWE). The
model introduced here is of Marshall-Olkin type. The marginals of the new
bivariate distribution have exponentiated modified Weibull extension
distribution which proposed by Sarhan et al.(2013). The joint probability
density function and the joint cumulative distribu- tion function are in closed
forms. Several properties of this distribution have been discussed.The maximum
likelihood estimators of the parameters are derived. One real data set are
analyzed using the new bivariate distribution, which show that the new
bivariate distribution can be used quite effectively in fitting and analyzing
real lifetime data
