In this research work, a continuous probability distribution as an improvement of Topp-Leone distribution was developed. Thus, density function and the cumulative function of the constructed distribution were obtained. We also show the validity of the new distribution. However, some properties of constructed distribution such as, survival and hazard functions, moment, and probability weighted moment and order statistics were derived. Parameters were obtained using method of maximum likelihood estimation.
