Thank you very much for this Nick. I however have an extension to the
question. What if I want to do the same exercise for say 100 subjects but
ensuring that for every 10 subjects then number of treatments are equal i.e
A=5 B=5.

Consider the results of 

. set seed 31103
. set obs 10 
. gen id = _n 
. gen random = uniform()
. sort random 
. gen treatment = cond(_n <= 5, "A", "B") 
. sort id 
. l id treatment
