Find the mean variance and standarrd deeviation off the bino

Find the mean, variance, and standarrd deeviation off the binomial disstribution with the given values of n and p.

n=123, p= 0.34

The mean ,u is = ( Round to the nearest tenth as needed)

The variance, o^2, is = ( Round to the nnearest tenth as needed)

The standard deviation, o, is = ( Round to the nearest tenth as needeed.)

Solution

let X~Bin(123,0.34)

then

mean=E(X)=41.8

variance=Var(X)=27.6

standard deviation=SD(X)=(Var(X))^0.5=5.3
