How to Calculate Combinations: A Clear Path to Understanding

To determine the number of ways to choose 4 gene sequences from 9, use the combination formula:
C(9,4) = 9! / (4! × (9−4)!) = 126

Similarly, selecting 3 protein interactions from 6 yields:
C(6,3) = 6! / (3! × (6−3)!) = 20

Final Thoughts

To find the total unique pairings, multiply these values:
**126 × 20 = 2
