(you can't use paper, you have to figure it out in your head)
i have a black triangle, a white triangle, a black circle and a white circle
. if i gave you a shape (triangle or circle) and a color (black or white),
the "frobby" items would be those that had either the shape or the color,
but not both. that is, in order to be frobby, the item must be of the
specified color OR the specified shape, but not both the specified shape AND
the specified color. i'm thinking of a shape and a colo |
