Problema Solution
The two spinners shown are spun once and each lands on one of the numbered sectors. What is the probability that the sum of the numbers in the two sectors is prime? (One sector is labeled 1, 5, 3. The second is labeled 2, 4, 6. They're split into 3 sectors.)
Thank You!

ok so lets list all number probabilities:
12= 3
14=5
16=7
52=7
54=9
56=11
32=5
34=7
36=9
so out of 9 possible combinations, we have 7 prime
7/9
