Answer 1

I'm sorry but I think there's an error in this problem. It says that only 73 people have investments in money market funds. But it also says that 38 people had investments in stock funds and money market funds and 36 people had investments in bond funds and money market funds. That would mean that 74 people had investments in money market funds and investments in stock funds or bond funds. The math doesn't make sense in my opinion unless there is something that I mean missing. Or do the first three numbers refer to people who only invested in a single fund?
