Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n equals 125n=125 , p equals 0.46

This is a matter of knowing the formulas involving the binomial distribution: Mean = n*p = 125*0.46 = 57.5

Variance = n*p * (1-p) = 125*0.46 * (1-0.46) = 125*0.46*0.54 = 31.05

Standard Deviation = sqrt (Variance) = sqrt (31.05) = 5.572252686
