I have set this table up in a spreadsheet and colored in the squares as they appear in the table above. I have not counted any number as a member of 2 categories twice. An example would be 36 which is a multiple of 3 and a perfect square.
I have answered the question as though the question took on the properties of a dart board: you through a dart and whatever you hit is counted either as prime, a multiple of 3 or a perfect square
That said, there are
primes: 2
multiples of 3: 24
Perfect squares: 4
Total number of choices: 12*4 = 48
Probability: 30 / 48 = 5/8 or 0.625
If you are supposed to use some other method of counting, please leave a note.
