Answer:
They are of same sex.
Explanation:
My guess about the gender mix of a group of eight 5-year-old s playing together is that, they are all of the same sex.
Is early childhood, children of same sex tend to play together in group. Not that they so not play with the opposite sex, but they prefer to play and be with their mates or group of same sex.
This improves and gets better as they grow, then they begin to have affinity for the opposite sex.
