โฆ Synopsis
Suppose X,, X,, ..., X, are independent and identically distributed random variables with absolutely continuous distribution function F. It is known that if F is standard normal distribution then (i) 2 X : is a chi-square with n degrees of freedom and (ii) nX2 is a chi-square with 1 degrees of freedom where i=-2 Xi. Here the above two propertiea are utilized to characterize the normal distribution. n

In this article a characterisation of the Gumbel's Bivariate Exponential Distribution is established on the basis of the propertiea of the conditional expectation of the component variables. The characterieing property is propoeed as the definition of lack of memory in the biveriate case.
