Hello
I have to generate random variable from exponential and beta distribution where a=4 b=7 for beta and lamda=0.5 while p=0.8 How can i generate mixture of both?

Check whether I have interpreted your parameters correctly, but it should look something like this:
lambda = 0.5;
a = 4;
b = 7;
pr_exponen = 0.8;
n = 1000;
e = exprnd(1/lambda,n,1);
b = betarnd(a,b,n,1);
u = rand(n,1);
mix = zeros(n,1);
use_e = u < pr_exponen;
mix(use_e) = e(use_e);
mix(~use_e) = b(~use_e);
figure; histogram(mix);
