There are 3 sums that can be formed using the 2 in the first set, 3 sums that can be formed using the 3 in the first set, and another 3 sums that can be formed from the 4 in the first set. Total of 9 sums.

Calculate all 9 sums. Count the number of sums that are at least 4 but no more than 6. Divide this count by 9.
