So first find out the pattern. As you can see it just minuses 2 each time. So first
18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.
So 2 is the ninth of the pattern, so 2 will be your answer.
Hope this helps.

Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Numbers on balls:
1, 4, 7, 7, 8
Try to find the sum of all numbers:
1+4+7+7+8 = 27
According to the rule of 3, any number is dividable by 3 if the sum of it's individual is divided by 3.
27 is dividable by 3, therefore any combination will result a number with a factor of three.
Prime number is the number that is only dividable by 1 and itself. Therefore, any combination using those numbers are not prime number.
So the probability is 0
