Hello how to normalize the plot in this AAD because its value is relatively high compare to FAR and MAR

here is my code please feel free leave some comments thank you so much AAD=Td

h1=(0:1:5);

y1 = pdf('Normal',h1,mu1,sigma1);

plot(h1,y1)

hold on

mu2=5;

sigma2=1;

y2 = pdf('Normal',h1,mu2,sigma2);

plot(h1,y2)

hold on

p1=1-p2

p2=0.1587

n=0:1:5;

Td=h1.*((1-p1.^n-p2.*p1.^n)./(p2.*p1.^n))

plot(Td)

hold off
