Question 481545: 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? The first is labeled 1,3,5 (equally sectored in 3 parts). Second Spinner is labeled 2,4,6 (also sectored in the 3 equal parts).

You can put this solution on YOUR website! 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? The first is labeled 1,3,5 (equally sectored in 3 parts). Second Spinner is labeled 2,4,6 (also sectored in the 3 equal parts).
---
List all the sums (there are 3*3 = 9 sums)
---
Count the number of prime sums.
---
Divide by 9
----
Probability = (# of prime sums) / (# of sums)
