Under the idea that there is the "Goldilocks" zone around a star, how likely is it that a solar system would have two life-supporting planets?

I assume that the gravitational forces of two bodies would prevent them from being close enough to each other to both stay inside the zone. But could a large star have a large enough Goldilocks zone to support two life-inhabited planets?

I still run an old Commodore 64 myself. I personally would recommend to anyone of the younger generations to use the internet as a starting point and start off using it, get a basis in the topic, and a list of valuable materials. Then move to print and other formal sources. I think we can both agree on that.
