Maths question - Moonwalkers

[budfox]

Twelve men walked on the moon. None were born in February, April, May, or December.

What are the odds that from a randomly selected group of twelve people, there are four months which none of them were born in?

[budfox]

Yes, I knew about the birthday thing, just wondered what the odds were of the above.

Glad I started an interesting discussion. I'm no mathematician but I do love to read about the US space programme and Apollo in particular.

Just hope that at 50 years old I live to see a man walk on Mars. I rate my chances as 50/50, the same as the chance that Mike Collins reckon Apollo 11 had of making a successful moon landing.
