There are 6 red and 8 green balls in a bag. 5 balls are drawn at random and placed in a red box. The remaining balls are placed in a green box. What is the probability that the number of red balls in the green box plus the number of green balls in the red box is not a prime number?

There are 6 red balls and 6 green balls in a bag. Five balls are drawn out at random and placed in a red dox. The remaining seven balls are put in a green box. If the probability that the number of red balls in a green box plus the number of green ball in the red box is not a prime number, is p/q where p and q are relativey prime, then find the value of (p+q).
