For probability distribution, we know,
Mean, 
= 
xf(x) = 0(0.4) + 3(0.6) = 0 + 1.8 = 1.8
We know, Variance, 
= (0-1.8)^2*0.4 + (3-1.8)^2*0.6
= 3.24*0.4 + 1.44*0.6 = 1.296 + 0.864
= 2.16
Thus, Variance = 2.16
Now, Standard deviation = √(Variance) = √2.16 = 1.47
Variance = 2.16 and Standard deviation = 1.47
The correct option is (A).

H.19 The psychoactive drug sold as methamphetamine ("speed"), C10H1sN, undergoes a series of reactions in the body; the net result of these reactions is the oxidation of solid methamphetamine by oxygen gas to produce carbon dioxide gas, liquid water, and an aqueous solution of urea, CH,N2O. Write the balanced equation for this net reaction.
