This is what I think...(Am I correct?)

P(answering and call waiting/answering machine)=(.50/.90)=.56 or 56%

**bobpursley**, Friday, October 19, 2007 at 10:02pmDIdn't the probem state that 50 percent have both? Am I missing something here?

I dont read a conditional probabality on the fifty percent.
