For a binomial distribution, the variance is
![\sigma^2=npq=np(1-p)=10*0.7*0.3=2.1](https://tex.z-dn.net/?f=%5Csigma%5E2%3Dnpq%3Dnp%281-p%29%3D10%2A0.7%2A0.3%3D2.1%20)
![\sigma=standard\,deviation=\sqrt{2.1}=1.449](https://tex.z-dn.net/?f=%5Csigma%3Dstandard%5C%2Cdeviation%3D%5Csqrt%7B2.1%7D%3D1.449)
(to 3 decimal places)
