Split a vector into two vectors randomly

hi, I have a vector that has 36 values and I'd like to split it into two vectors randomly. ( the first vector has 25 values and the second has 11 values ).

I have written this code but when i have repeated values in the original vector, i will not get 11 samples in the second vector because of this command

I really appreciate any help guys. Kind Regards.

Why not do this:

t = original_vec(randperm(Total_Samples));
First_vec = t(1:25);
Second_vec = t(26:36);
