I don't know how to approach this problem. Please help!

**economyst**, Thursday, September 20, 2007 at 9:47amFor these types of problems, I like drawing a probability tree.

That said, I really dont understand your question. With 3 babies, at least 2 will be of the same sex (BBG or BGG) possibly all 3 are the same sex (BBB or GGG). Could you clarify?

**PsyDAG**, Thursday, September 20, 2007 at 12:37pmIs this a trick question? "One" cannot be the same sex. It takes at least two to be the same.

I hope this helps a little more. Thanks for asking.
