The shooting of a 14-year-old girl and two adults outside a Brooklyn baby shower was a robbery attempt gone wrong, officials said yesterday.

A 34-year-old woman, a man and the girl, who was wounded in the chest, are all expected to survive.

They were standing outside Universal Resort, on Church Avenue near East 48th Street in East Flatbush, at 9:30 p.m. Saturday when they were attacked.

There had been no arrest as of last night.
