A question about Ginkgo Biloba trees:

I have five very young trees. Three are cuttings and therefor very likely to
be male. The two others look like to be grown from seeds. Now my question:
how many Ginkgos from 100 seeds are male and how many are female? I vaguely
remember there would be more female than male plants, but what are the exact
numbers?
