Tom has been given six numbers—1, 2, 3, 4, 5, and 6—to make a decal. The numbers are in
different sizes and only certain sizes look good together. Tom will not combine sizes that will
not look good together. The following statements about the appearance and arrangement of the
numbers are true:
The 2 will not look good with the 6.
The 1 will look good with the 3 or the 4 but not with both together.
Tom must use the 1 or the 2, or both.
Tom may use only three symbols on the decal.
