Why does this code not work?

%USE MONTE CARLO METHOD TO CALCULATE PROBABILITY OF FAILURE OF WIND TURBINE

%The given limit state function for the given is

%g = P= 2.652*10^-8*D^2.4299*V3.0116- 0.5;

%Given :

D =90 ;

V = 6.672408424 ;

mean_D = 90 ;

mean_V = 6.6724 ;

sigma_D = 10.29023 ;

sigma_V = 0.67708 ;

%Now use normrnd function

n = 10e6;

D = normrnd(mean_D, sigma_D, [n,1]);

V = normrnd(mean_V, sigma_V, [n,1]);

%Create for loop

K = nnz(2.652*10^-8*D^2.4299*V^3.0116-0.5 < 100);

P_fail = K/n

D =90 ;
V = 6.672408424 ;
mean_D = 90 ;
mean_V = 6.6724 ;
sigma_D = 10.29023 ;
sigma_V = 0.67708 ;
%Now use normrnd function
n = 10e6;
D = normrnd(mean_D, sigma_D, [n,1])

D = 10000000×1

93.6215 100.2214 77.4233 103.6873 86.7063 93.5225 78.1190 82.3651 97.7291 80.3734

V = normrnd(mean_V, sigma_V, [n,1])

V = 10000000×1

7.0408 6.4080 6.3675 6.5585 5.4430 6.4935 5.3796 7.1606 7.6568 6.1422

%Create for loop
K = nnz(2.652*10^-8*D.^2.4299.*V.^3.0116-0.5 < 100);
P_fail = K/n

P_fail = 1

use element wise operator .^ and .* in the expression
