male/female ratio

hey guys, this may seem like an exceedingly paranoid and newbie question but if i grow 4 plants from seed whats the normal female/male ratio? i'm freakin out cos if i put 8 months of effort in and get a heap of males i will be really pissed off.
cheers

could really get any combo of male/female.
after about 6wks theyll start to show preflowers and you can determine sex from them.
my avatar is a pic of one of mine at about 6wks showing the preflowers.

50/50 each plant.
