I have never heard of any species that can do both. One would assume that a creature would either lay internally fertilised, (or unfertilised) ova in the form of eggs, or produce live young. For a creature to do both would be most unusual.
live birth not eggs are mothers who are mammals
Approximately 20% of animal species give birth to live young. This includes mammals, some reptiles, and a few fish species. The majority of animal species, such as most fish, amphibians, and invertebrates, reproduce by laying eggs. Thus, live birth is relatively rare compared to egg-laying in the animal kingdom.
Not all snakes lay eggs. Some species give birth to live young.
Snakes can either give birth to live young or lay eggs, depending on the species.

They lay eggs, rather than have live young
Both. Most do give live birth but some species lay eggs
It means that the animal will give birth to live young. Mammals are live-bearing. If an animal gives birth to eggs, it is not.
Snakes can lay eggs or give birth, depending on the species. Some snakes lay eggs, while others give birth to live young.
Either - it depends on the species. Some lay eggs and some give birth to live young.
It depends on the species. Some snakes lay eggs - some give birth to live young.
Not all cockroaches lay eggs. Some species give birth to live young instead of laying eggs.
