For instance, a given probe ATTCAGGTC with locate the DNA sequence TAAGTCCAG and form 2 or 3 hydrogen bonds with the opposing nucleotide based on which complex it is. I believe the A/T complex has three hydrogen bonds and the C/G complex has 2 hydrogen bonds. Therefore, in our example probe we will find 23 hydrogen bonds, which gives the probe its stickiness.
