**bobpursley**, Monday, October 29, 2007 at 6:25pmThe minimum number will start with the 15 percent who do not have a telephone:

So 150 of 452 have a computer, but no telephone.

The next group has to be having a telephone and a computer, but not cd player.

300 do not have a cd player, so you can take these 300 and make them owners of a computer.

That leaves 2 people who have to have all three.
