MC bedrock edition strongholds

I don’t believe so, I believe only under normal villages, as the Minecraft Wiki says here.

In Bedrock Edition, strongholds generate randomly throughout the world. They sometimes generate under a village.

I hope that answers your question.

While its true that strongholds can generate under villages, I don't think it applies on abandoned ones. I have never seen a stronghold under one at all. You could try, though I doubt a stronghold would even generate under it.

You'll have a better chance that the stronghold would be under a village, but I'm not exactly sure if ¹/₁₀ is really the approximate chance for a stronghold to be under a village.

I have, in fact, seen a lot if strongholds under abandoned villages.

The 1/10 chance applies to regular villages and abandoned villages.
