Meyer rolls two fair, ordinary dice with the numbers on their sides. What is the probability that at least one of the dice shows a square number?
this is what i found
(square numbers for this are 1,4,9... and 9 is too big so just 1 and 4)
36 possible rolls
20 out of 36 will display al least one '1' or at least one '4' 20/36 = 5/9
