Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

On the planet Philogynos, men are so despised that any woman giving birth to a boy is not allowed to have any more children, how ever many girls she has had before. On nearby Misandros, however, they hate men so much that any woman having a girl is considered to have attained perfection, and will consequently have no more children.

Assuming each baby is equally likely to be male or female, what are the ratios of the sexes on both planets?
