In This Paper We Have Considered Diverse Distribution to Acquire the System Reliability of a N-Course System. the Assessment of Reliability Is Considered Primarily For Course Systems. For This Reason, a Few Distributions Are Considered Specifically, Exponential, Weibull, Gamma, Rayleigh, Lindley, Uniform and Two-Point Distribution. at That Point some Notable Distributions In Particular, Exponential, Gamma and Weibull Distribution Are Utilized to Assess the Reliability of N - Course System. the Numerical Values R(1), R(2), R(3) and R3 Have Likewise Been Processed and Given In Unthinkable Structures to some Particular Values of the Parameters.
