Meyer rolls two fair, ordinary dice with the numbers 1,2,3,4,5,6 on their sides. What is the probability that at least one of the dice shows a square number?

x 1
x 4 where x = 1-6 less the 1-1 4-4 counted twice = 22 rolls out of 36

x 4 where x = 1-6 less the 1-1 4-4 counted twice AND the 1-4 4-1 counted twice = 20 rolls out of 36 (Thanx, Alan !)
