We study the periodicity of the solutions of the rational difference equations system of type π‘₯ 𝑛 = π‘Ž / 𝑦 𝑛 βˆ’ 𝑝 , 𝑦 𝑛 = 𝑏 / π‘₯ 𝑛 + 𝑝 βˆ’ 2 ( 𝑝 β‰₯ 1 ), and then we propose new exact procedure to find the probability density function of the solution, where a, b, π‘₯ 0 = 𝑁 and 𝑦 0 = 𝑀 are independent random variables.
