The only prime number of the list of values given is the value 13. This is because the only factors are 1 and 13. Something like 24 isn't prime because 2 is a factor.
The probability of rolling to get a prime number is 1/6 because there is one prime out of 6 total values listed.
The probability of spinning on "G" is also 1/6 because there is only one section labeled "G" out of 6 sections total.
Assuming both events are independent, we multiply the probabilities to get (1/6)*(1/6) = 1/36 which represents the probability of rolling a prime number and spinning on G.
