Yes, probably, definition
Yes, probably, means that some circumstance or factor related to the death could probably have been prevented. “No, probably not” indicates that everything reasonable was most likely done to prevent the death, but the child would still have died. A designation of “Team could not determine” means that there was insufficient information for the team to decide upon preventability.
Yes, probably, said Fatty. “That means that someone might have heard him just then. We’ll find out. Any more?”
