the pdf of the mixture is just the weighted average of the pdfs of the beta and gamma, something like
p_beta = 0.8; % probability of beta
X = 0.1:0.01:1; % whatever X range you want
mixpdf = p_beta*betapdf(X,{beta parameters go here}) + (1-p_beta)*gampdf(X,{gamma parameters go here})

OK, X can be your random data if you want the pdf's of those random data values.
I am pretty sure that I don't really understand what you are actually trying to compute.
