Abstract
In this paper a new probability distribution will be built and produced known as the(The Transmuted
Survival Frechet-Frechet Distribution) with three parameters (β, θ, ⋋), by using a new formula which is
(Transformed survival function )formula in which the Frechet distribution,Some structural properties of
the new models are investigated. The new formula may serve as a flexible transmuted to other
distributions for modeling survival data, Where the probability function of the new distribution
transformed (TSF) has been proven, some statistical and mathematical properties have been examined,
and the parameters of the new distribution have been estimated using the MLE method
